midcan5: I don't think anyone has figured out yet what causes homosexuality. For public policy purposes, suffice it to say that it is not generally something that one chooses to BE. No rational person would make such a choice, and homosexual activity is revolting to the average mature man. THIS is the reason why homosexuals and homosexual activity has been scorned and criminalized for most of human history. Even if the various holy books are simply made-up nonsense, the condemnation of homosexuals and homosexual activity are rooted in this instinctive revulsion by normal men.
On the other hand, homosexual BEHAVIOR is 100% voluntary, just as heterosexual ACTIVITY is voluntary. Without homosexual ACTIVITY, any laws against sodomy, etc., are MOOT and of no effect. So the statement that "People are persecuted for BEING HOMOSEXUAL" is utter nonsense. Nobody knows that anyone else is homosexual absent overt, voluntary behavior.
Homosexual behavior is sexually PERVERSE. Fact, not opinion. The male sexual organs have a purpose and function that is easily observable (i.e., to facilitate fertilization of an ovum), and ejaculating in another man's ass or mouth is a perverse bodily function, even if it feels good or "natural" to the dispenser.
It is not possible to create a legal definition of "homosexual." Many homosexuals are not sexually active, or are sexually active as heterosexuals; many heterosexuals, placed in extreme circumstances, are known to commit homosexual acts. Which of these groups of individuals could be called "homosexual" as a matter of law. Only one: active homosexuals. And what about when they are older and are no longer interested or able? Are they still homosexual?
Lesbianism is a whole different matter. It IS possible and even common for a female to identify as lesbian even with little or no sexual attraction to other females. There are a number of reasons why this happens, many of which would be unkind to mention. For example, Linda Hunt and Rosie O'Donnell are "lesbians." Really? Or are they just so repulsive to men that their only hope of a loving relationship is with another woman who doesn't care about their repulsiveness?
Many lesbian couples are completely inactive, sexually speaking.
Trans-sexualism is a neurosis, bordering on psychosis. It is the firm belief in a fact that is false. There is NO MEDICAL OR BIOLOGICAL BASIS for this belief. Indeed, biology mocks such a claim, making it necessary to go to extraordinary measures to modify the body to promote the pretense of the opposite gender. In patronizing such a false belief, society is doing the individual no favors. The suicide rate - even in an "accepting" environment - for trannies is ten times the normal suicide rate. Put that in your pipe and smoke it.
