Why cant gay people just be theirselves?

I'm sorry but i am so sick of all these gay people pretending to be straight and go off to marry a woman and pretty much ruin some poor girls life, not to mention their life to. Its sad that they all allow themselves to be brainwashed by all these stupid bigots, and people full of hate isnt it? I cant believe some of them are willing to do that JUST to get a thumbs up from people, who's opinions and hatefulness about gays didn't matter to begin with. It really does make me kind of sad because i dont think anyone should ever have to live a life their not happy with. Gay or not. Sorry if that didnt make much sense but i felt like getting that off my chest..
