Call coming from inside the house!
What’s funny is you can’t really become a leftist without understanding enough theory to realize Propaganda of the Deed is a dead end. I don’t know if I’d be bold enough to call it counter revolutionary but for a revolutionary in the modern age it should not be undertaken. This is not 1878, you can’t just shoot a mine boss, and it’s not like we’re living in a global communist utopia because that shit works. It didn’t.
So basically when these murderjunkies pop off the odds of them actually being a leftist are slim to none. You might have a person who is dabbling in leftism or festoons themselves in hammers and sickles but that’s just some bandwagoning, really. You might have a radical liberal who is radicalized along a conventionally “left” vector like gay rights or abortion access but those aren’t really “left” opinions.
Which leaves us with the elephant in the room: the right wing stochastic terror machine and its apparatchiks.
