Stupid I could pity. Simply stupid people are society's wards.

These people are malicious, and vote for policies sold on the basis of cruelty for cruelty's sake to people who aren't them.

Their malice Trumps their stupidity, especially because most of these people don't suffer some cognitive deficit, but have been trained to be willfully ignorant with for profit media using cruelty as the training incentive. That's the stupidity you choose.
