She talked to the Gay guy?
Anyway, lol, I took the opposite way, I went to a major with a lot of girls and the majority of them isn't like that at all(actually, I tend to avoid the girls who are interested in me JUST because I took the said major). I think it's just the novelty effect. After it wears off, you'll be fine. You can always pretend to be Angelina Jolie in Hackers.
Talk to them normally, ask real questions, let them know that you are really interested in the stuff. You will weed out the idiots eventually. Aren't you first year anyway? Wait until you get to your third year, and see what happens.
