"Proper supply of chromosomes", "female and male species". . . Christ man, it's no wonder you have so little regard for science. Maybe one of the things they need to tighten up on in schools is science education? Or was your educational institution based entirely on using gut feeling to make sociological and psychological judgments? Once again, and I can't say this enough, what is natural is not necessarily what is right! We were created out of a filter made of mass death and extinction, that's what natural selection is. If we based our society solely on what is "natural" it would make Nazi Germany look like Mr. Rogers Neighbourhood. I agree that it wouldn't be necessary to promote awareness for folks who wanted to come to school with a gimp mask on or something. The difference between that and defending fetishistic behaviour is that transgenderism would be considered a lifestyle rather than a paraphilia. Taxpayer-funded schools in a secular society should teach kids to be open-minded and respectful of others in public. Your contempt of reason is really the culprit here. The fact is that if there's no harm that will come from the behaviour of an individual, they have the right to be protected against harassment. In an educational setting, the protection should have more to do with consciousness-raising than with threatening punishment. Also it's interesting to see the fundamental insecurity underlying your position. On the one hand, these people are wrong in the head, on the other you're afraid that it will spread through imitation. Fifty years ago the man who invented the computer, and who through cracking the NAZI enigma code possibly did more to win WWII than Eisenhower, was imprisoned for privately committing homosexual acts. Even though he deserved a knighthood Alan Turing was locked up and pumped full of estrogen to reduce his libido. As a homosexual he was considered at the time to be mentally ill so he could not be trusted with state secrets. He ended up killing himself. I'm sorry to tell you but THINGS CHANGE, and the educational system will be at the forefront. If your quaint notions of family values are threatened by the schools telling your children that a boy dressing like a woman isn't mentally ill, and deserving of basic respect and courtesy, well then that's just tough I guess.
