Wow, talk about weird fantasies... dude, you aren't my type.
But duly noted you couldn't answer the question of how teachers handle the REALITY that gay people have children, too, through adoption, surrogacy and artificial insemination. I think you probably have a hard time with this reality your damned self.
Again, works on the assumption that kids are little robots...
So little Timmy goes home and asks his parents, and the next day, he's screaming at little Sally that her mommies are going to Hell because Jesus hates them!
"Well, Sally, I'd like to tell you your parents are fine and Timmy is going to grow up to be a complete shithead, but Governor DeSatan says I can't."
