Should I be honest about my sexuality in College?

First off im not America so im not in that cultural context im actually from a little stinky poor country somewhere in latin America, I go to a real prestigious univeristy its filled with people who have diferent taste its just diverse.

And that is what amazes of this country this freaking high tolerance that people havce for one another, of my 18 years living ive never heard a case of hate crime its ridicolous how tolerant we, I used to believe that until today.

Today I was in a class and we started to talk about (the teacher and my classmates) to just gossip arround kids who dont go to class because they are bussy getting laid (yes our teacher is that liberal), then she said that they found two boys, she didnt say what they were doing but you should of seen the disgust on her face.

She said that they sent them to disciplinary something, and then she went on to talked about how people dont want to come here (the university) they dont want to come because they think that the university lets gay couples kiss.. all I could say is whats so wrong with that....?

The guys there are fairly homophobic the tolarate everything and I neab everything: Different religions, nazis, blacks anything.. except sexual diversity, I had the dilution tha tI would be honest about my sexual orientation because I had the hope that once they saw how cool a gay guy was(im not a gay steryotype at all) they would somehow open up theyre eyes now im really planning not to that now... its awefull..

What are the cons and pros of comming out in a homophobic school, one con is that ill probably only have girl friends, I mean theres nothing wrong with that but I like video games, computers and just hanging out with guys in general... so you think I should just be always honest with my sexuality? hope someone understood this
