'Progressive" / "left wing" homicides?

I was wondering about this. There is a fairly large amount of killers with beliefs that could be classified as "right wing", conservative or reactionary. Like the nationalist Anders Breivik, antifeminist Marc Lepine, various Islamic extremists. I was largely inspired by [You must be registered and logged in to see this link.] thread that lists mass shooters who do seem to have some ideologies, instead of just wanting to kill people. Though in my opinion people like Eric Harris and to some extent also Pekka-Eric Auvinen weren't much of ideological killers since actual social darwinism doesn't really work like Auvinen seems to think, and I'm quite sure that Eric liked Nazis mostly for edginess' sake, since in order to be a racial supremacist or a nationalist you need to actually like some nation or race, and significantly more than others.

But I digress. The killers who do have ideologies tend to have certain ideologies much more often than others.

The only criminal with a political motivation I know that could be called left wing or progressive was Valerie Solanas, who attempted to kill Andy Warhol and promoted female supremacy.

So do you know any criminals with similar beliefs? There has to be some. I'm curious.
