Centrists here (lots on piefed, some of the main developers for a piefed app hardcoded leftist instance blocks without telling anyone until they got caught, that is their vibe a "hallucinated" center) lose their mind about leftists even when the world outside is drowning in radical rightwing fascist movements openly advocating for violence, racism and fascism. Also did any of them warn you that there are rightwing VERY VERY toxic parts of the fediverse that mainly don't connect to the bigger communities because they are simply too violent and toxic to federate with normal people?
sigh
You will run into stupid leftists here, maybe that will be a new experience for you if haven't because they were excluded from all the other places you have been but shrugs the idea that this is some problem that needs to be shoved in the face of new users in their welcome in post is kind of pathetic and says more about these "centrists" than it does about .ml at this point. Even if it is a new experience so what, there are plenty more intelligent leftists with nuanced views, this vision of tankies is a caricature on purpose in a frankly alarmingly cynical way especially given the state of the world and who has power.
