Those debates just show why Grokipedia is needed. Truth seeking is the opposite, it's when you demand crowdsourced consensus that debates become endless and stupid.
Here's a cut and dried case: the BBC admitted recently to broadcasting faked video of a Trump speech. It wasn't a mistake and the lying was institutional in nature, i.e. an internal whistleblower tried to get it fixed and BBC management up to the top viewed it as OK to broadcast video they knew was fake. Even when it was revealed publicly, they still defended it with logic like "OK, maybe Trump didn't say that but it's the sort of thing he might have said".
So the BBC can't be considered a reliable source, yet Wikipedia cites it all over the place. This problem was debated here:
https://en.wikipedia.org/wiki/Wikipedia:Reliable_sources/Not...
The discussion shows just how stupid Wikipedia has become. Highlights include:
1. Calling The Telegraph a tabloid (it's not)
2. Not reading the report ("What exactly was editted incorrectly?", "it's just an allegation")
3. Circular logic: "This just seems like mudslinging unless this is considered significant by less partisan publications" but their definition of "less partisan" means sources like the BBC, that just lied for partisan reasons.
4. Shooting the messenger for not being left wing enough.
5. Not fixing the problem: "Closed as per WP:SNOW. There is no indication whatsoever that there is consensus to change the status of the BBC as a generally reliable source, neither based on the above discussion nor based on this RfC".
Wikipedia is as broken as can be. It institutionally doesn't care that its "reliable sources" forge video evidence to manipulate politics. As long as left wing people turn up to defend it, there is no consensus, and nothing will change even if those people clearly don't even bother reading what happened. The death of Wikipedia will be slow, but it will be thoroughly deserved.
