I personally don't aspire to authoritarianism, as I hate being told what to do but I'm pretty realistic just from having worked a lot: most people can't really be trusted (for many reasons, largely not due to their own shortcomings I think) and any kind of effort to steer society away from capitalism is going to necessisitate a lot of very, very heavy handed behavior for a time. Just look at anti-vaxxers in the USA. Are you just going to ask them to fucking stop? What about the people clear cutting forests? The guys who habitually underpay and exploit labor?

I think it's just that a lot of dumb 4channoids tend to be weirdo edgelords (which never left me, I'm just grotesque about it) and as such aren't really enamored or impressed by "civility" and I tend to feel some anarchists/liberals I've interacted with are extremely naive with regards to hyooman nature. If you spent your formative years looking at fucked up shit on /pol/ you can pretty quickly realize that humans are capable of some monstrous shit and that Nazis and the right in general tend to lean into the worst of that (and I know this to be true because I've posted with those assholes) so it becames very hard to want to confront that kind of evil with anything but equal and greater force. Even fucking Fanon makes mention of that.

Beyond looking at like gore and liveleak I've personally just had a lot of negative experienced with humans in general so like....I'm not convinced everyone can be "talked" to or reasoned with, and while I'm scared of engendering the same abuses we have now like there are only so many ways to deal with people who refuse to get their shit together
