Janadele is probably referring to this type of teaching, and Fox News' spin on it.

First of all, the children are being taught the truth. They are being taught facts about nature. Conservative religious types don't like the scientific truth about many things. The spin that the conservatives put on this is just a misinterpretation of what the guy in the video is saying.
I'm not sure how to convince theists of this ilk that they are wrong when Fox contributes to the confusion of the bubble zone that feeds into this stuff.
The teacher is
emphatically not teaching them that "
Young children ... can choose to be a boy or a girl -- or both". He is trying to explain that some people appear to be boys on the outside, when in fact they feel inside like they are a girl, and we should not bully them, rather accept and understand people for what they are. People have a right to be who they are.
The spin is just bigoted unpleasantness. I think it's a great idea to let kids in on these ideas at an early age.
ETA: I must say that the cognitive dissonance that this kind of input represents to the highly indoctrinated theist is very likely overwhelming. That is understandable, and there may be no way back for them. But I have to ask one question of Janadele, "Why would I try to convince anyone that this video is a desirable way to teach children if it is morally wrong?" From what you know about me, am I morally corrupt?
It is a chance for children with gender confusion to grow up leading a happy and productive life, rather than being relegated to the closet. Please give me a reason other than a religious one to deny a child this chance in life.
