Look I don't know if it is different in the states, but here in the UK if you present people with a complete package which looks right and makes sense, and moreover you come across as comfortable with yourself, mostly people will accept it at face value and/or just live and let live.
THE ONLY time when you get grief is if people sense that you are not comfortable with yourself or they think you are putting on some sort of false persona/act. Then they will give you a hard time in order to try and unmask "the real person".
So - make sure you are comfortable with yourself. Don't be too "in your face" about anything, be a nice person, and generally things will be ok. Oh and it helps if you can manage to ignore or laugh off any little comments that you get - because any bully looking for a victim will only pick you if they get the impression that you care or are isolated. Thus the best defense is to be amiable and easy going with a devil may care attitude.
As I say things may be different in the states - but over here, in my experience, a college or university environment is way way way the EASIEST one to deal with and if you cant hack it there then you will almost certainly also struggle in real life because in real life people are often far meaner than a bunch of students.
I think 90% of the fear of this is in your own imagination. I do hope that is of some help.
