"See their actions just prove that homosexuality is a learned behavior. If are just "born that way", why this push to indoctrinate younger and younger children? "
Their excuse is that you need to teach about it because all the straight people are bigots eager to harm "gay children."
I think there is something to be said for this argument, since I recall distinctly that effeminate boys and boyish girls were treated horribly when I was in school; however, I think that all harrassment should be educated against, at age-appropriate levels. Teaching that homosexuality is "natural" and "normal" is not the way to go, IMO.
Fat kids and dumb kids are also picked on. The natural tendency is to bully the weak and look up to the strong.
