Eh, authoritarian isnt necessarily increased the more extreme you go. The foaming at the mouth anarchist who wants to go full john brown on a prosperity preacher isnt necessarily authoritarian, homicidal and fucking crazy? Yes. Authoritarian? No.
But this is probably due to the fact a lot of those types are usually smart enough to hold their tongues. But tankies will happily go on and on about how theyll kill all the folks who dont fall in line blah blah blah. If I ever have to deal with a tankie IRL id probably flop between laughing and wanting to fight them.
