You’re not being a jerk, you’re being pedantic.

Ignorant is absolutely the better word, and I should have used it.

I think, however, that people are far more capable of gaining intelligence than we give them credit for. I don’t believe that IQ is assigned at birth, and it’s been shown that the entire idea of IQ testing is extremely flawed.

There are people born with learning disabilities, of course, but that’s a whole other conversation.
