Check out this recent article by Dennis Prager, "The Challenge of the Transgendered". He explains that transgender people (who behave and/or dress as a member of the opposite sex) challenge Judeo-Christian values by rejecting their natural identities, part of God's creation. The radical homosexuals ally with them because they share the goal of undermining traditional moral values and sexual roles. Excerpts:
"It is remarkable that activists on behalf of gay and lesbian acceptance always include the transgendered. What, after all, do the transgendered, who are usually heterosexual men, have to do with gays and lesbians?
"The answer is that activists understand that their primary goal -- equating same-sex sexual behavior with man-woman sex -- can only be accomplished if other Judeo-Christian and Western sexual norms are also rejected.
"That is why the very word 'sex,' when referring to male or female, has been changed to 'gender.' And society at large has accepted this linguistic change as if it were insignificant. The change on application forms, for example, from 'Sex: M or F' to 'Gender: M or F' has gone unnoticed. But it is a huge change. In the sexual activists' world, 'sex' is fixed and objective; 'gender' is fluid and subjective....
"One of the major values of the Old Testament, the primary source of Judeo-Christian values, is the notion of a divinely ordained order based on separation. What God has created distinct, man shall not tamper with.
"As examples, good is separate from evil (attempts to blur their differences are known as moral relativism and are anathema to Judeo-Christian values); life is separate from death (in part a reaction to ancient Egypt, which blurred the distinction between life and death); God is separate from nature (see part XVI); humans are separate from animals (see part XV); and man is separate from woman. Blurring any of these distinctions is tampering with the order of the world as created by God and leads to chaos. So important is the notion of separation that the very word for 'holy' in biblical Hebrew (kadosh) means 'separate,' 'distinct.' "...
If a man gets a sexual thrill out of wearing women's undergarments in the privacy of his bedroom, that is not society's concern. It may be his religion's concern, and, religious or not, it may be his female partner's concern (one wonders how many women married to cross dressing men are pleased by the sight of their man in a bra and panties). But it is not society's concern...
However, when a man does this in public, he has publicly blurred the man-woman distinction, and society has the right -- and the duty, if it cares about Judeo-Christian values or simply cares about not confusing children as to sexual identity -- to say this violates a norm that society does not wish violated.
The war waged by cultural radicals at universities, in state legislatures and in courtrooms against the very distinction between male and female is one of their most significant attempts to undo the Judeo-Christian foundations of American and Western culture. And they know it. That's why fighting to blur gender distinctions is so important to them.
