Please note, I am straight, these are just in first person.
I'm gay, so I must have STDs.
I'm transsexual, so I must be a hooker/whore
I'm bi, so I must want to screw everyone I see.
I'm lesbian, so I must have a sex tape.
I'm gay, so I must be a prissy guy that acts like a girl.
I'm lesbian, so I must make out with a hot girlfriend on a webcam.
I'll edit these as I think of more common stereotypes for homosexuals/transexuals. I completely believe that each and every one of these is sickening. God, someone needs to do something about the homophobia that seems to be spreading all over the country. And people call homosexuality a disease! Yeah right, take a look at yourselves, all you homophones out there. If a homophobe is reading this, please note that I don't mean to be offensive, I just believe that that way of thinking is wrong.
