Their Berserk Button is other people's stupidity.
OR Suffers Fools Poorly. Needs More Examples. Rolling Updates.(Needs a Better Description ?)
"Some people took her for cold, thought she was aloof. Not a bit of it. She just despised idiots, no time for fools. Shame really, otherwise we'd have gotten on famously."Have you ever head a remark so spectacularly dumb that it just made you angry? Do you have a low tolerance for Cloud Cuckoolanders or ditzs? While some might respond with sarcasm, pity, or even despair these characters just can't handle the dumbness around them. They seethe, they rant, they curse or even resort to violence. When this trait kicks in it can be the last straw for a normally reasonable person or an intense enough irritation to be their Berserk Button - especially for the Only Sane Man or those Surrounded by Idiots. Of course, this reaction is sometimes totally justified when the act of foolishness is or has put people in danger. The results of becoming Enraged By Idiocy can vary from a Dope Slap to a Cluster F-Bomb to acts of violence. As with any loss of temper, this usually becomes a weak point or dangerous distraction for the angry party - making it a handy tactic for anyone merely playing dumb. Obviously a Sub-Trope of Berserk Button. Mostly characters who are the Only Sane Man or Surrounded by Idiots tend to have this.
