It's just typical lib cope.
They make a boogeyman and then they tell one another campfire tales about how tankies are like this and how tankies do that.
It's really endemic especially across the progressive to radlib spectrum. (The conservative and more reactionary end also do it but it's in a different way - they appear to just make baseless claims that are post-hoc rationalisations to justify what they want to do but that's a different discussion.)
But yeah, the radlibs and centrists will gather round and assure one another that the tankie will simultaneously never actually read theory, they'll worship Marx/Stalin/whoever, they treat Capital like scripture, they actually support any sort of movement which drapes itself in a red flag, they can't argue and they'll just yell at everyone to read theory, they will enter into mainstream discourse and subvert it to turn people into Marxists if you let them, they spend all of their time online in circlejerks and they are no threat to anyone, they are a powerful voting bloc and they are an existential threat to Biden's reelection, they are all Chinese/Russian bots, they are all brainwashed victims of a political cult, they are all power-hungry opportunists who are just using socialism as a vehicle to achieve their power fantasies, they are all children who do not understand the real world, they spend all of their time reading and arguing about theory rather than doing anything effectual.
And they all sit around patting eachother on the backs for regurgitating these stories, each more fanciful than the last, and none of them seem to notice the contradictory claims.
It's a bit like the libs who cry fascism over Trump and when you ask them what did they do to resist fascism when Trump was in power you get cheap excuses and blank stares.
Like if I'm a brainwashed child that is a cult-victim then why would you berate me and throw all sorts of accusations at me?
If I treat communist theory as scripture and quote it at people then how is it that I also do not read any theory?
If I support anything that is draped in a red flag then why not start a "communist" wing of the DNC to funnel votes to Biden?
If I don't actually achieve anything and I'm relegated to an online circlejerk then how can I be a subversive infiltrator that will pervert good, honest liberal discourse to trick people into becoming communist (by yelling at people to read theory??) and how is it that I can influence the presidential elections?
It's just ridiculous.
