Your approach seems condemning and judgmental. I struggle with the idea of teaching children to behave in this manner. Especially over something so private. People do all kinds of deranged things that are clearly hurtful and destructive. Homosexuality is neither of those. What exactly is the downside of teaching tolerance?
If I recall, you mentioned that this perspective is not based in any faith, so explain to me how you feel homosexuality is destructive. Also, you do understand that this behavior occurs with other animals...right?
Oh....and your signature is offensive.
