Gay marriage should be allowed.

"The greatest gift a husband can give his children is to love their mother, and the greatest gift a mother can give her children is to love their father. That is what will keep the proper balance in the family and make their home environment secure. That is what will free the children from their primary fear, which is to be abandoned by one of their parents. Why do they fear that? Because that is what has happened to so many of their friends at school."Marriage is supposed to have the ambitious goal of providing children with a nurturing and reassuring base from which to learn to face the world. Therefore, parents must not only be good persons, not only a man and a woman (so as to provide the dual role models psychologists say they need), but also so unshakably devoted to each other that their mutual love can withstand all the temptations and shocks that life will hurl at them, as well as the abrasion of living with each other.To this end, sexual passion and the bewildering differences between the sexes jointly play a vital role. As Chesterton put it:The differences between a man and a woman are at the best so obstinate and exasperating that they practically cannot be got over unless there is an atmosphere of exaggerated tenderness and mutual interest. To put the matter in one metaphor, the sexes are two stubborn pieces of iron; if they are to be welded together, it must be while they are red-hot... Therefore, as Fr. Vandenberg goes on to emphasize, sexual intercourse is not merely a permitted "perk" or a reluctantly tolerated means of procreation but rather a vital and holy part of marriage -- a divinely sanctioned means of demonstrating and intensifying conjugal love to make it withstand the rigors attendant upon raising children.*Fortunately, as with all animals, men and women have the proper equipment for such activities. The corresponding parts of the male and female body interact quite neatly for both mutual pleasure and procreation.Not so for homosexual men and women. Whether or not there is anything wrong with their desires, they simply don't have the proper apparatus to fulfill them. They must resort to clumsy makeshifts, like cargo cult devotees trying to make airplanes out of straw. Alternatively, they submit to grotesque operations, trying to alter their bodies to suit their desires. The artificiality of these attempts to mimic normal sexuality will inevitably distort the emotions that arise from them and will tend to adversely affect any children living with them.Homosexuals who engage in such desperate expedients shouldn't be condemned for wanting to do so. As the psychoanalyst in Kurt Vonnegut's God Bless You Mr. Rosewater explained:Let's assume that a healthy young man is supposed to be sexually aroused by an attractive woman not his mother or sister. if he's aroused by other things, another man, say, or an umbrella, or the ostrich boa of the Empress Josephine or a sheep or a corpse or his mother or a stolen garter belt, he is what we call a pervert. Let us hasten on to the admission that every case of perversion is essentially a case of crossed wires...In fact, there is neurological evidence that at least some homosexuals are wired differently and cannot help their proclivities. Others contend that homosexuality may be one of the aftereffects of sexual abuse during childhood. In recognition of such factors, the Catechism of the Catholic Church proposes the apparent paradox of condemning homosexual acts while urging that people afflicted with homosexuality be treated with sympathy.But we cannot debase the whole concept of sex and marriage merely to oblige them. The objective of what a gay activist has called the ""war we've already won" is to reduce marriage to a lowest-common-denominator status that will inevitably include polygamy, which is already being touted on ABC-TV as "normal" and being campaigned for in Canada. That's too high a price to pay for making homosexuals feel better about themselves.
