Lemmy was made by and is developed by Marxist-Leninists as a response to Reddit. You aren’t going to find any pro-west Marxist-Leninists. The admins of Lemmy.ml are also Marxist-Leninists, so in general Lemmy.ml is going to be far less pro-west than Lemmy.World, which is a Liberal Instance.
Lemmy.ml has fantastic FOSS and Privacy communities, so not all members are Marxists, but generally liberals coming from Reddit go to Lemmy.world, while Marxists go to other communities, in my experience.
