Technically yes as it was a communist attempt to destabilize America.

I don't mean technically, I mean literally is there any kind of parenthetical connection between social justice and the kinda of 'for the lulz' trolling of the late nineties/early two thousands?

In truth, communists do not believe in freedom or equality, they merely dangle those lies in front of the gullible and retarded to get them to destroy themseleves.

I think it's a bit more complicated than that. For one thing, you gotta keep in mind that the most dyed-in-the-wool communists, including Marx himself, were ironically about as "bourgeoisie" as they came, so besides the inevitable NIMBYism, they also have/had little to know understanding of how money works in the real world, as opposed to their little gated community bubbles.

Add to that a touch of egomania, and you start to see why they unironically believe they could reshape human thought into something more "equitable," in spite of the numerous failures of their ideas to bear fruit. Their predecessors just didn't have them to make it work, so of course it failed (/sarcasm).

I suspect they see 'freedom' as an illusion meant to control the gullible, but when you look at their actions, there doesn't seem to be an objection to making people 'equal' by making them equally miserable. So long as the playing field is 'level,' I doubt the average rank and vile gives it much more thought than that.

What do communists get out of this? The power to make everyone as miserable as they are.

Power in general, but also they get to fluff their own egos.
