Lemmy is a link aggregator and the Fediverse’s left-wing replacement for Reddit. Politically, it fills a role similar to Truth Social, just on the opposite end of the spectrum, whether users like to admit that or not. In practice, Lemmy is deeply ideologically fragmented. lemmy.world tends to attract liberals and social democrats, while lemmy.ml, which brands itself as Marxist-Leninist, is effectively a hub for authoritarian-left enthusiasts: open admirers of regimes such as China, Russia, North Korea, and Cuba. The hostility between these camps is constant and mutual. ML users dismiss World users as “libs,” while World users fire back by calling ML “tankies.” ML views World as hopelessly moderate and compromised by liberalism; World views ML as extremist, dogmatic, and dangerously apologetic toward authoritarian states. The irony is that both sides are radical in their own ways. One faction is entrenched in authoritarian apologism, while the other occupies an insulated, ideologically homogeneous bubble that still sits far outside mainstream political discourse.

This post is a good example of said slander/infighting, as MLs are inherently not dogmatic, and having consistent values is painted as being homogenous.
