I notice this especially with my Norwegian learning. People are rude, call me names, or make fun of me on Reddit for using the wrong word or “en” vs “et” or using a direct translation because I don’t know how they say it in Norwegian, like saying somethng like «Ingen av bedriften din!» instead of «Dette er ikke din sak» (according to the casual version of Bing Translate) whereas a Norwegian-speaking Fediverse member would just say something like “You’re doing good, but it’s actually _____.”
Reddit is big enough that it’s a microcosm of humanity. The Fediverse hasn’t reached that level yet.
When I was on Reddit, most of the subreddits I hung out on were small, supportive, and friendly. A few I monitored weren’t — on purpose, so I could see what was going on in other places.
Funny thing is, for the most part, I’ve found matches for all those subreddits on Lemmy communities— although I had to browse through a bunch of hosting services to build up the same level of diversity.
