I replied to someone saying that the USSR defeated the Nazis saying that it was a group effort. Got into an argument and called a Nazi repeatedly because “I was mad that the USSR defeated the Nazis and hated them for it” which is ridiculous. This isn’t the first time that’s happened on Lemmy. What’s up with that?
You are free to make your own instance and defederate.
That is indeed a good idea, but doesn’t fix the problem for the new people coming to Lemmy via popular instances like lemmy.world.
