Most of people, if not all, come from Reddit (me included). Depending on how you behaved there, that behaviour can be brought to other places, like Lemmy/Kbin. People have the right to defend their own ideas or opinions, but that doesn't mean they have the right to be rude, argumentative, mean or whatever.

Most of communities/magazines have rules to avoid people be very out of boundaries, like no bigotry or no hate speech, and I'm happy that those rules are enforced and respected. But I think a big mistake of moderators is that they stop writing more rules because bigotry and hate speech are the real evil. What about good manners? What about being nice to each other, even when disagreeing? What about remembering the human? If I were on lemmy.world and you were on lemmy.ml, and I called you stupid because you like oatmeal... is that bigotry? Is that hate speech? What is it? How do you define that behaviour to write a rule not to follow?

Beehaw is great because there is one single general rule to all communities: be(e) nice. Other communities can put other rules to be more specific about what is tolerable and what is not, but being nice is always at the top. I wish other communities/magazines/instances did the same thing.
