Well, this is a start. ;-)
I know this is very politically incorrect, but I know someone who had a little boy in preschool who was encouraged to cross-dress and pretend to be a girl at the preschool. Today he is very effeminate, and it won't surprise me if he is actually gay. The influence of a domineering mother and a preschool teacher who encouraged him to "get in touch with his sexuality" should be horse-whipped.
