What is sinful about homosexuality?<quoted text>
The Torah speak of homosexuals in the world. The sin is to act on it. It could be to do with the fact that wasting sperm is considered a sin.
Is homosexuality more damaging or more sinful than incest?
Is anal sex wrong or harmful? Why?

Wasting sperm is a sin - so you say.
Did the patriarchs of the Tanach know the difference between sperm and semen and did they know about the structure and chemical composition of sperm and semen?
Isn't sperm wasted when a man masturbates or indulges in recreational sex with his wife/partner?
