I honestly don’t mind if someone bases their beliefs based on flawed theory or books, as that does show some degree of engagement with actual texts and leaves the room open for recognizing why it might be flawed via future reading or discussion.

What I was mostly referring to were people who claim to be Marxists/Anarchists/whatever, proceed to not read any theory whatsoever and just roll with what they imagine the theory to be, usually based on some surface-level discourse floating online. Now that’s where one can find true incoherent bangers
