It wasn't a hostile discussion or anything, i didn't even go full "the kulaks deserved it" (although the mod that single-handedly banned me did go full "the kulaks did not deserve it"). I just laid out plainly and calmly that revolutions are inherently authoritarian, that Luxemburg said "the revolution will be as violent as the ruling class makes it necessary" and that there's one Trotzki quote i 100% agree with: "If the October Revolution hadn't succeeded, the world would have known a Russian word for fascism 10 years before Mussolini's March on Rome". Basically the whole "Jakarta Method" train of thought laid out clearly and without calling anybody names.
Note that this was on an explicitly left-leaning server that does not allow cops and troops to join. Also after several days of another poster starting destructive, aggressive bad faith arguments in the politics channel until a number of users went "disengage" on her and the channel had to be frozen until recently, when she immediately started being hostile and arguing in bad faith again, which got her not one, but two warnings from the same mod without further consequences. Meanwhile, when i defend AES without attacking anybody, that's apparently too much for her to handle. No advance warning, no "sis, you're talking to me as a mod here", not even a notification that i got banned.
The best part is that according to screenshots a friend just sent me, she's now completely going off about "authoritarians". The nerve some people have.
Sorry for posting pointless internet drama here, i just needed to vent.
I mean, sorta?
The distinguishing feature of anarchists is that they do in fact want revolution and are willing to shoot guns over it. While there is no such feature of ancaps, the NAP is explicitly anti-revolutionary, and opposes all capability to effect change within the system through any means other than the use of money and property.
So yes. I can kinda see that comparison. The only thing I will say however is that the anti-authoritarians that can be pipelined leftwards are usually still in favour of use of authority for some things, such as enforcing the age of consent. Whereas the libertarians seem to be against authority in even that case too. This distinguishes which group of anti-authoritarians that pipeline left vs which group of them pipeline right.
