Why are there so many gays now and why should it be taught in schools?

I personally don't like gays because I don't believe in it. Call me a bigot or whatever Idc. If you have a right to like gays then I have a right not to. Clearing that up quick ! I think everyone has a right to do what they want. But to force it on peoples kids is crossing the line it should be up to the family to teach their kids
