Your account has repeatedly been posting snark and flamebait and attacking others. Here's one example of many, from a different thread:
https://news.ycombinator.com/item?id=50367498.
It's true that your account is not the only one breaking the site guidelines, but that doesn't make it ok for you* to do so. Pointing the finger at others doesn't help.
(* I don't mean you personally, of course, but any of us)
It's true that we don't moderate in every case where the guidelines are broken, but that's for the simple reason that we don't see everything that gets posted—not even close—and we can't moderate what we don't see. It is not because we're secretly agreeing with one side more than the other, though it's common for politically passionate users to jump to that conclusion (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...).
> Either ban all political comments or none
That's not how HN works. There's a long body of experience and many past explanations about how it does work: https://hn.algolia.com/?dateRange=all&page=0&prefix=false&so....
If you want to familiarize yourself with that material and then have still a question that hasn't been answered yet, I'd be happy to take a crack at it. But since all the obvious objections, such as the one you raise here, have been answered many times over many years, I think it's fair to ask people to read some of those answers first.
I've now attempted to address all the points you've raised, so I'd like to add one of my own: I believe we've banned you before, and if you keep violating both HN's rules and its intended spirit, we're going to ban you again. If you'd please take the spirit of the site more to heart and fix this so we don't have to ban you, that would be better.
