Why would I want to talk to someone who would hate me and think I was evil if they knew me better?
Muggle Studies? At Hogwarts? What a bizarre idea. There was certainly none of that back home. I expect it would be considered a trifle insensitive, seeing as some people have muggles for relatives. I do know that things change at school over time, though. In 1849 we have Duelling classes, but a wizard I spoke to from the next century said that he had something else when he was at school. Defensive Arts? Something of that sort.
