Sorry to leave this off CW, but I gotta say this once:

Don't be an asshole on my instance. Don't go out of your way to troll people. If you don't get along with someone, leave them alone. This is not Twitter, where being antagonistic is a strategy in the absence of moderation. There is no reason to spend your time hurting people here.

I don't care who started it. I am especially unsympathetic if the people you're being a jerk to are commies.
