While I guess that what you mentioned is a part of it?
It's more that I tend to have my doubts about just how much education(versus home life/any give kid's social circle...) can really fundamentally turn a kid into something that they never would have been.
Take what seems to be a lot of the conservative angle on LGBT folks and how they should play into any child's education.
Let's say that we could magically create a world where their worst fears had been realized, and schools had carte blanche to try to "Teach..." kids to be gay.
Does anyone actually buy into that education alone would result in even most straight kids not eventually saying "Look, I know what you said I am, but I seriously believe that I am straight..."?
I think that, for the most part, kids are just going to wind up being their individual selves no matter how you attempt to used education to shape what they will wind up believing.
