He’d rather own the libs than admit he’s being treated like every single anarchist in history.
Nah, with terminally online cosplayers, the result is almost always "Mask off, actually was aligned with tankies all along" rather than "Principled opposition getting betrayed after alliance of convenience". That's more of a real-world anarchist pitfall.
Tankies give them asspats and don't demand anything of them, while evil liberals and demsocs actually demand some small baseline of action. If one's interest in anarchism is more the sense of community than ideology, they pitch towards tankies hard. The reverse is rarer, despite tankies also being largely of the same mentality, because anarchism is less inherently tribalistic than ML insanity about orthodoxy and revisionism, making it less appealing to a tribalist mindset already immersed in such concepts.
On the other hand, I've known a number of tankies through the years who pitched hard-right once they found community with online right-wingers.
