It all begins with the compromising acceptance of a false premise: There is no such thing as homosexuality; it is homoeroticism. Sexuality must be inherently functional; that is where it begins. (Forget the Bible if you like; see real science on Sexual Reproduction.)

There is no functional form of sexuality that can occur between two persons of the same sex. Homoeroticism is a narcissistic fetish that happens to focus on another person rather than an inanimate object. I pity such persons, but they cannot make me call a pig a cow.
