Actually I just solved the problem for gays and genderqueers.
What they need to do is start with children's education. They start teaching the differences between vagina and penis early on. Here's the catch; you switch the labels on vagina and penis on random days every week.
Then you start teaching them about the gender confusion. Expose them to pictures of men dressed as ballerina wearing boots and rough looking dikes and then show them as transexuals so they get confused as to which one is a male or female.
Then you introduce the shit smell from anal sex at an early age with their favorite foods.
Then everyone's gay and fucking retarded.
Congratulations!
