So what exactly is wrong with being married, heterosexual and either a girlie girl or a manly man?

It's one thing to teach equality, but this is going too far. There is nothing wrong with teaching children their differences, and how to accept other people's differences. Do they not realize that these children will one day grow up and notice there are very distinct physical differences, boys being physically stronger for example? What they are really doing is setting these children up for confusion....
