As long as you are able to differentiate between bad language (skills), cultural differences, and bad behavior. On Reddit that's basically the same. Many things may sound harsh, but are often just expressed frustrations, voiced in an imprecise way. And often, nuance is lost in translation. Many foreigners aren't used to nuance like Americans are.

Many Europeans won't hold back. Like, you tell your neighbor that he's an idiot directly to their face. Out of love; how else would they know. Apparently, none of their friends told them. Poor fellow. Just an example. I've learned that Americans won't do that, for whatever reason. they would just call them idiots wherever they are not around, and keep smiling. ;)

That really is the case. Back when I went to war with feddit de for constantly leaving shitty comments I was surprised at how few people I had to block from that instance before the abuse stopped coming my way. Now that you mention it, 20% of the population sounds about right.

Tangentially related, but yeah, some usernames one can remember after seeing them for the umpteenth time and then one spots the same people all over the hot topics 😅 that doesn't only apply to toxic ones, it's just that an active core of Lemmy community is still small enough, a nice time to be a part of it
