What is the general vibe on here towards actually existing socialism as well as the ideas towards reformism?
I can only speak for myself but so-called AES is just capitalism. It can be capitalism that is far far better than the U.S or other imperialist countries, but I'm not a communist that cheers for improvements to Capitalism. And what is there to speak of with "reformism"? It's a dead end that doesn't lead to Socialism and is the norm.
As an aside, both Lemmy.ml and Lemmygrad are largely full of what I'd called revisionists, meaning simply the refusal to acknowledge that Socialism has been defeated and supplanted by state capitalism where it once briefly existed. The actual communists (i.e they at least agree with Leninism) in imperialist countries are largely revisionists so it's not surprising that's what you see online among English speakers. However, Lemmygrad is a dogmatic echo chamber. If you want to hear nothing but pro-AES sentiment and walk on dogmatic egg shells, that's the instance you want. Lemmy.ml is ran by good people (the developers) and seems to have decent moderators despite my political differences. I at least come across a variety of positions and whatnot.
