I wasn't evading the question, I was clarifying my original statement. No, I did not mean that people come out of the womb engaging in sexual conduct. But my original statement - that are born gay just like they are born blonde or brunette - stands.If you have to evade a clear question in order to maintain your position, the position merits re-evaluation.
So, when a male whose sole desires and conduct are exclusively heterosexual goes to prison and is brutally gang raped, thereafter exhibiting desires and conduct that are homosexual, was he a born homosexual?
In the situation you mentioned he incurred psychological trauma from being sexually assaulted, not from it being a homosexual experience.
Sexual preference and gender identity can change throughout the course of ones lifespan just like one's natural hair color can change throughout the course of one's lifespan. But just because a baby was born blonde and later ends up being brunette does not mean he chose to be a brunette. In the example you mentioned the individual is still not choosing to be homosexual; his change in sexual preference is due to psychological trauma which is still a biological cause.
The bottom line remains that sexual preference is not a choice. It is biological, just like many other traits, and thus children should be taught not to discriminate against those who were born different or became different through no choice of their own.
While I generally believe that states should have ultimate control over their own educational policies I'm wary of allowing any state to encourage or perpetuate such discrimination against someone due to their biology. This would be a case in which federal oversight would be fully justified in making sure that all the people of this land are treated equally.
