Cross dressers are about 10 to 20% of the male population and even higher among women. That's a lot of disturbed people.
Yes, well trying to work out the whole spectrum of emotions you're allowed to feel respective to your gender in our oppressive society by wearing different clothes you can put on or put back in your dresser as you choose isn't quite the same as sewing your dick back on when a machiavellian MD helped you chop it off in violation of the hippocratic oath.
Children should not be reading anything...
ANYTHING that alludes to that latter conclusion as being anything else but patently insane.
You're pointing out the difference between transvestites and transsexuals as was I.
In today's world, Children are as well informed about sex as most parents. Attempting to hide any sexual subject just perks their interest. By the time they leave grade school they know about homosexual and heterosexuals sex, transgender, and gay marriage. They have kids in their class with gay parents some kids are already identifying themselves as gay. Practically all of them are exploring their sexuality in one way or another which includes masturbation, pornography, and sexual experimenting with the same and opposite sex. Books described in this thread aren't likely to have any impact on the sexual preference of kids.
