Same kind of humorless dolts who inhabit left spaces on reddit and are a uniquely a product of reddit’s culture of total conformity. Leftblr used to make fun of them all the time. Speaking from my own experience, I am a tankie, or at least most would accuse me of being such. But I didn’t pass the Lemmygrad purity test, and they blocked my registration because I said gender is fake and gay on my application (gay used as a pejorative). Not saying I didn't or deserve a warning but yeesh context matters. Which is my personal experience, but if they are that way toward other communists, they are going to be way harder on perceived liberals so most people don't like seeing their posts day to day.
