Lemmy skews left, and censors moderate views / comments. You're generally ok in various areas to be openly hostile towards certain demographics -- typically white people, cisgendered people or men in general. You can use pejorative language to describe those groups with impunity. You can get banned from lemmy sites for questioning left-leaning narratives. Functionally, it's not that dissimilar.

Censorship is used in part to cater a site to its market niche / audience. Whether you agree/disagree with a sites censorship approach, is generally based on whether you're in that target audience / intended marketing bubble. If you've never been censored on a site for moderate views, you're just squarely in the target group.
