When I started German in college, one of my teachers, who was a graduate assistant, said when he decided to major in German there were a few people who thought that was weird and asked him if he was a Nazi. I find that incredibly rude, but I have wondered from time to time if other people have gotten comments like that when people find out you are studying German. I was in music, so it made more sense for me to study German, I guess some people think it is not a useful language outside the arts or something.
