.world and .ml like to beef over their politics (generally liberal vs more leftist/Marxist)
Aside from that, people are generally pretty kind and won’t bash you for having left-of-center politics. If you’re a conservative, though, I’d expect downvotes. There just aren’t very many around on Lemmy. (And I personally think things are better that way.)
Say I’m on Mastodon, and someone posts a reply to a meme that I think is funny. I take a screenshot of their post to send to other people or post on Lemmy. Is it more polite/respectful/appropriate to censor out their name and handle (to respect their privacy) or leave it in (to give them appropriate credit for their idea)?
Littering, especially cigarette butts. Nothing sends me into a blind rage faster than seeing someone flick a cigarette butt out their car window. Not littering is SO easy, the bar is on the floor, and yet so many people just don’t care at all.
