There's a difference between being rude and being ableist. Why do chuds suck? It isn't because they're not smart, which wouldn't exactly be in their power to change were that the problem.

It's because they're hateful, closed-minded, unwilling to listen, immature, reactionry, cause tangible harm to our comrades, and stand in the way of any progress or revolution. They choose to do these things and can choose to do different things.
