I think it's very arrogant and pretentious to call other people 'stupid' and I try to refrain from doing it. We all know people who are much smarter than us, surely we must sound stupid to them. Besides, one can be stupid for one thing (say mathematics) and shine for something else (raising kids or playing the trumpet).

That being said, I can't help thinking a lot of people are stupid, especially when I read news or youtube comments. It's amazing how so many people can be dumb, mean, uneducated and bitter.
