Playing fair? No one talked about playing fair. They're not gonna play fair and they're absolutely gonna start attacking you eventually. But it is NOT the same thing if they start attacking you when you have no legitimacy, and if they start attacking you after you have reached the point when you can have some sort of organisation and can mobilize people.

Also I forgot to say, the point isn't that some normie who happens to see this is gonna be scared away. The point is that people repeating and upvoting this stuff leads to a certain (big) subset of people really taking that rhetoric to heart. We all know how the internet works. Some guy sees that sort of stuff and takes it super seriously, so then he starts shouting about killing people at ever opportunity they get irl as if that's gonna help. They may even end up carrying it out. And again, this is bad. It is bad to overestimate the acceptance or militancy of the left right now. It is extremely bad to completely ignore these considerations. It is also extremely bad to paint things in broad strokes and act like things are already as bad as they can be or it doesn't matter if x happens because it's gonna happen anyways etc. Maybe it's useful as propaganda but it's not what you should believe because it is not true and failing to see that leads to terrible analysis that doesn't get results. History is littered with examples of people who made the same mistakes and ate shit.
