It's even sadder when people do get that chance, but prefer to keep their heads in their asses so they don't have to think.
God, yes. I don't like ignorance in people, but I hate chosen ignorance. I think it's one of the most despicable things a person can do--choosing to remain ignorant about something because knowing too much about it will make their life more difficult.

When I meet an ignorant person, I try my best to treat them fairly and, if a more difficult subject comes up, I'll try to calmly explain to them why I think they're wrong about what they're saying. If I meet a person who has chosen to be ignorant, well, I usually lose my patience immediately. There's no excuse for being deliberately ignorant.
