Leftist Infighting

You still haven’t addressed my main criticism of auth-left, which is the fact that mass murder completely discredits everything the left stands for.

Because you have mendacious critics coming from literal nazis in many cases, there is nothin to address. You also arrived at purely anticommunist point of view that we "like" the mass murder. No, liberal, we don't, marxist revolutionaries just never allowed it to stop them and cripple the revolution if it was needed. Something that anarchists also did in the two rare cases when they managed to do something resembling revolution and weren't subordinated to the forces of reaction. What you present looks like the liberal pacifism, and afaik is not espoused by any real historical revolutionary movement.

Wow… that’s how you see us? Really?

Yes, literally, because it's truth in most cases, definitely the ones like you, demanding explanation for what nazis tell you we did. And not even entire truth because it misses the fact how ultras and anarchists are very often used as the tools for reaction, from the Kronshtadt rebellion through the ongoing COINTELPRO program to recent cases in Syria and Ukraine.

Some exception were the case, like some Maoists here and there or Posadists in Cuba, but the maoist struggle never brought any fruit even despite sometimes decades of tries and Posadists got ultimately dissolved by their inherently unstable ideology.

As you said we most likely won't make eachother mind.
