HN's guidelines are not ideologically driven. They're designed to help the site achieve its mandate of being a place for intellectually curious conversation [1]. People can't be in curiosity mode and battle mode at the same time—the nervous system doesn't work that way. (They probably can't be in curiosity mode and ideology mode at the same time either, but that's not really where we draw the line.)
When accounts are using HN for battle, smiting enemies, lashing out, and generally contributing to burning this place down, we ask them to stop, and if after repeated warnings they don't stop, we ban them. That's not because we disagree with them ideologically—we ban all accounts that do this regardless of what side they're on. It's because it's the only way to preserve this community and prevent it from destroying itself the way internet forums usually do [2,3]. The goal is for HN is to stay interesting, and scorched earth isn't interesting [4]. We've tried to be true to this core value from the beginning; it hasn't changed and won't change for as long as we can manage to keep it. We do get better over time at articulating it and iterating on the ruleset for keeping it [5].
Actually, the irony is that such accounts resemble the corresponding enemy accounts (and vice versa) far more than either set resembles the majority of users here, who are coming to the site in curiosity mode.

[5] The guidelines have changed a lot in the last year or two. For example, they used to say "Be civil", but now they say "Be kind". That wording reflects the intended spirit better. There are many other things like that, but none of them have changed the core value of the site—they're all an attempt to serve and preserve it better.
BTW, I would personally ban all politics from HN.
Banning all politics from HN is not an option, for reasons I've explained many times. See the links here: https://news.ycombinator.com/item?id=25723581.
Until the companies being discussed have the right to use force against you your argument holds no water.
I mean Trump did everything in his power to become the next Putin.
Your concern about sending people to the Gulag is pretty far-fetched.
When this came up yesterday, someone raised the common objection "why not just ban all politics then?" If anyone has that question, the thread is here: https://news.ycombinator.com/item?id=25711241
