Stupidity always irritates even stronger than some targeted violence, because violence is still possible to at least understand - what's the point, that you are trying to achieve something, you hate, but you at least understand why they do it, what's the target, and when a person commits blatant stupidity, you know what he's doing worse to yourself, by and large.
