s and bis?

It does get annoying at times. Most of the time I just shake my head but some days it really gets on my nerves. I hear it a lot because I'm bi. Since they see me checking out girls most people just ume I'm straight so they don't think about it and start spouting the anti-gay crap right in front of me. Like just because I looked at a girls legs that should automatically mean I hate gays?
