I love it when I'm watching debates or discussions, and guys will hear something they don't like from a politician.
So instead of attacking what the politician says, they'll attack the man himself.
The "nut" for example, might actually have a point. But the debater lacks the mental prowess to comprehend or attack with merit, the argument put forth by a high profile person who is obviously smarter.
So, the debater will call him a name, and laugh about it, high-five his fellow nimwit friends. They won't even know what the argument is about - but hey - it gave them a chance to insult someone who is infinitely more important than they are, in the world.
Funny stuff. Epic self-owning by non-thinkers in a thinking man's game.
