The vibe is exactly like the astroturf shit that flooded reddit in 2016. Endless criticism of Democrats in the US, while never mentioning US conservatives for some odd reason. That's why I get from the "Jor Biden really bad, genocide! Don't vote for him, vote 3rd party!" They come to US left/democrat/liberal spaces and try to convince people to not vote for Biden, but where are the efforts to convince people to not vote for Trump? And then this "you say everyone is a russian bot lol!!" thing is also exactly what the shills on reddit did.

It's not that they don't oppose capitalism so much that they'll ignore any sense of ideological consistency on their quixotic quest to make sure that everyone knows America is Bad.

Spot on. Whatever that's called, that sounds like much/most of the hexbear and ml instances.

... America has proven time and time again that it will break any moral barrier to attack anyone even suspected of being a socialist,

Sadly, you're right. More to the point there are many examples of the US knocking down anything or anyone even suspected of threatening capitalists. Whether that's unions within the US, governments leaning too socialist (yet being democracies), or whatever else. I know you know this; I just felt like venting.

it's just so evidentally self defeating you have to wonder if there are any true believers at all or if they're all sockpuppets run from a Russian speaking basement somewhere.

When they all come out with new talking points about the same time, all bearing remarkable similarity, and coinciding with notable (geo)political events, and brigading certain posts, it sure makes you go, "hmm."

I don't think it's about capitalism/socialism/communism at all for a lot of them at this point. They have a fairly simple ideology: the enemy of my enemy is my friend. And their enemy happens to be their own government.
