People who actually want to progress as a species
Don't you think that's a bit of a vague definition? I figured Progressivism meant something more specific. If it's simply referring to an ideology that has some sense of promoting the progression of humanity to an improved state, then someone who believes that a sharply delineated and stratified society according to IQ would lead to the progress of humanity could be called a Progressive...
have a tendency to not want to Kill other people.
Well, I'm not sure that always avoiding killing people under all circumstances will best aid an ideology of progress. Unless this is a spiritual progress that necessitates pacifism? Any idea of progress with any worldly element to it I think could be easily obstructed by a strict refusal to kill.
Anyway, assuming you didn't actually mean for Progressivism to be something so broad and we actually do have some common understanding of what it refers to: given how much contemporary Progressivism is seemingly founded on a narrative of tension between oppressors and oppressed, I have witnessed quite a number of Progressives advocating for violence in some form or another, even if most of them probably didn't have the guts to act it out.
Aren't we always the ones being mocked for being SJW's?
Look up videos aimed at criticizing SJWs on YouTube and you'll see a good deal of violence associated with them.
The lib-hippie-pro-environment-save-the-wales muh-fuckers are the violent ones, according to MG?
I don't see the lack of intellectual integrity in that. Remember the part about opposition between the oppressed and their oppressors? Well, whales are oppressed and Republicans are oppressors.
