There are a lot of decent people there and participating can feel really worthwhile to me but there are a lot of very angry people and even 1% of crazy angry toots can wreck my mood and I feel I wouldn’t want to participate otherwise.
One kind of behavior I can’t stand is people who call other people “fascists” indiscriminately because they are comfortable in their own skin or think we should have a police department or because they are a landlord evicting a tenant who didn’t pay the rent, or whatever. Much of the time I agree or largely agree with them on a lot of issues but it’s the hate I can’t stand.
So I am really quick to block on expressed hate, particularly when associated with certain issues that quickly get flagged on Hacker News as it seems many participants immediately resort to name calling against anyone who disagrees with them in the slightest or even expresses uncertainty on the issue.
You could make the case that these people really deserve a correction and that, who knows, the way they are they are driving people away from their side and helping “the fascists” get elected (for any political activity I think you have to ask the question of “who does this really help?”). This behavior is self-reinforcing and unfortunately these people surround themselves with other people who do the same things and many of them respond quite hatefully when you call out their behavior so I’d be doing nothing but arguing with these people and getting exhausted… without the block button.
