Even something as clear-cut as "the provided source doesn't support this claim at all" becomes an uphill struggle to correct. When it comes to anything related to politics this problem is also exaggerated by editors selectively opposing changes based on whether they apply a desired slant to the text.
I've also noticed that a few of these editors seem to be deliberately abrasive towards new users, perhaps with the hope that they'll break a rule by posting insults in frustration. The moment that happens those editors quickly run to the site administration and try to get said user banned. Wikipedia's policies are increasingly treated as a weapon to beat down dissent rather than a guide on how to contribute positively.
This is amplified by the fact that active editors socialize with each other heavily behind the scenes, and over a period of many years you end up with a core group that all desire to apply the same slant.

One thing I should clarify is that Wikipedia's purpose is to aggregate the current general view on things. So even if you know something is true personally, you cannot put it in unless you can find a reliable place where someone has documented it. In the cases I have there I had to first find the appropriate backing references before I could make something happen so it's not a trivial fix. Getting Makoto Matsumoto in there took me many hours because I know only a tourist's amount of Japanese.
I've also edited controversial articles (the Mannheim stabbing, one of the George Floyd incident related convicts) successfully.
Anyway that's my resume. Bring me the work you need done and once I've got a moment I'll see what I can do (no guarantees, I have a little baby to care for).
This is where I would disagree, the model really doesn't work for politics and current events. In those topics Wikipedia may be better described as "The world according to a handful of (mostly US-based) news outlets". There's been a prolonged effort to deprecate sources, particularly those which lean to the right, so it's increasingly difficult to portray a neutral perspective reflecting multiple interpretations of the same topic. Instead excessive weight is given to what a majority of a select group of online sources say, and that's not necessarily trustworthy.
Most obviously it's a model which will fall flat when trying to document criticism of the press.
Like any consensus-based thing it's pretty loose. It's unlikely that EN wikipedia had much of a position on the reliability of the Asahi Shimbun newspaper, for instance.
As an example, when I resurrected the Makoto Matsumoto article, I mirrored it to my personal wiki[0] in case it is deleted from the original. Another loss I lament is that of Chinese Numbered Policies[1] which I think is a genuinely interesting list and a meaningful categorization that I will eventually re-create on my personal wiki.
I'm a Wikipedia inclusionist which means I want as many true things there as possible in a way that represents the truth as accurately as possible, but it's a collaborative effort and that means that sometimes I don't get what I want.
Any way, as you can see from my earlier experience, I seem to have a skill of getting facts into Wikipedia when others do not, and I have a personal desire to see them there as well. So if you want to list a couple of the examples you had trouble with I can see if I can help. I know you said "politics and current events", but hopefully there are non-emergent situations that you can describe because evolving situations require more attention than I'm able to apply at the moment. I will still try, though. As an example, the Salvadoran Gang Crackdown had some ridiculous language on it that I removed[3] that was clearly an attempt to insert a left-wing (as it is in the US) political slant.
To be clear, I have no affiliation with Wikipedia (beyond the fact that as an auto-confirmed user I have the user privilege to create articles without going through AfC). I just have a personal interest in fact recording[2].

It does all hinge on that important list of acceptable vs unacceptable sources. In the last few decades there's been an increasing trend for news outlets to take a political position and decline to report on stories which would damage that position, which becomes most obvious whenever the US holds an election.
Speaking of norms, the Hacker News community will flag and downvote any comments of mine that mention that our 10 month old did not receive the COVID-19 vaccine. I think that's clear evidence of some kind of political bias. But that's this community's norms. I don't care as much to convince them as I do to fix Wikipedia.

Anyway, I understand if your experience trying to correct Wikipedia might have been at a different time, so you may not recall right now, but if you ever recall, my email is in my profile. I collect a list of these things and when I have a spare moment I try to make some progress.
I gave them a fair shot a couple of times, but they're unreasonable and unmoved to listen to reason or experience they don't actually possess.
I'll take curated information that is better and rigorous every time.
This works very well when there's a clear non-partisan issue with the text, like a logical inconsistency or the citation doesn't line up with the claim or the prose is just sloppy or unnatural.
If someone is trying to push biased sources, good luck.
The I-swear-it-isn't-a-cabal of highly-active editors knows policy better than you do, and they will continue to conveniently know policy better than you do no matter how much time you spend studying it. (And if you study it and then try to do your business anonymously, they will consider it suspicious that you know anything about policy and demand that you log in to your nonexistent long-standing account.) And that policy allows them to use highly biased sources because they are on they "reliable sources" list, except it isn't really a single list but rather some sources are restricted in applicability, unless it's one of them using it inappropriately. And the bias of those sources doesn't disqualify them as long as it's properly taken into consideration by whatever arcane rules, except this doesn't happen in practice and nobody will care if you point out them doing it, as long as it serves their purposes.
Meanwhile, the way sources get approved as reliable is generally that they agree with other reliable sources. Good luck trying to convince people that a source has become unreliable. You aren't going to be able to do it by pointing out things they've repeatedly objectively gotten wrong, for example. But they'll happily spend all day listing every article they can find that an ideologically opposed source has ever gotten wrong (according to them, no evidence necessary).
And it all leans in the same direction because the policy-makers all lean in the same direction. Because nobody who opposes them will survive in that social environment. There are entire web sites out there dedicated to cataloging absurd stuff they allowed their friends to get away with over years and years, just because of ideological agreement, where people who dispute a Wikipedia-established narrative on a politically charged topic will be summarily dismissed as trolls.
On top of that they will inject additional bias down to the level of individual word-choice level. They have layers and layers of policy surrounding, for example, when to use words like "killing", "murder", "assassination" and "genocide" (or "rioting" vs "unrest" vs "protest"); but if you compare article titles back and forth there is no consistency to it without the assumption of endemic political bias.
WP:NOTNEWS is, as far as I can tell, not a real policy at all, at least not if there's any possible way to use the news story to promote a narrative they like.
And if the article is about you, of course you aren't a reliable source. If the Wikipedians don't like you, and their preferred set of reliable sources don't like you, Wikipedia will just provide a positive feedback loop for everything mainstream media does to make you look bad. This will happen while they swear up and down that they are upholding WP:BLP.
I've been watching this stuff happen, and getting burned by it off and on, for years and years.
The stalking, censorship, and unwillingness to contribute to topics deemed as "controversial" is unreal. People might not believe, but wikipedia truly is one hell of a cesspool.
There is just too much bureaucracy for beginner editors nowadays. The whole baptism of fire that you need to undergo to be part of the oligarchy is just not worth the hassle.
