Bryan Caplan gives a number of apolitical reasons to hate politics. I agree with them all, but want to add one more. Here are his:
I hate the hyperbole of politics. People should speak literal, measured truth or be silent.
I hate the Social Desirability Bias of politics. People should describe reality as it is, not pander to wishful thinking.
I hate the innumeracy of politics. People should focus on what's quantitatively important, not what thrills the masses.
I hate the myside bias of politics. People should strive to be fair to out-groups, and scrupulously monitor in-groups, to counteract our natural human inclination to do the opposite.
I hate the "winning proves I'm right" mentality of politics. Winning only proves your views are popular, and popular views are often wrong.
Last but not least:
To these I would add: I hate how people treat politicians as personal saviors. I can't even understand how people can permanently glue a politician's name to the bumper of their car.
