Lemmy is populated by far left Americans who were banned from Reddit for extremism. Strict ideological conformity is required or you’ll get actual death threats. Don’t go there unless you want violent communist revolution and hate discussing interesting ideas.
Most people on Lemmy are in favor of killing all rich people, which I’d consider a far left position.
You can find that on Reddit too. It’s just this community is much smaller, so these voices are more prominent on lemmy.
