Via Huffington: William K. Black: Algebra for Dummies: Mathematical 'Proof' of the Inferiority of Homosexuals

Most forms of open revulsion for despised minorities have been banished from academic literature. But the academic campaign against rights for gays is proud about its descent into ever more virulent attacks on gay people and homosexuality.

One stream of the attacks seeks to prove that gays and homosexual are inferior. The effort has been lead primarily by ultra-traditional Catholic scholars that have attempted to create a "new natural law" that would support the traditional Catholic positions on sex -- that masturbation, all gay sex, contraception, all sex between unmarried adult straights, and oral and digital sex by straight married couples are all grievous sins. However, George W. Dent, Jr., a law professor at Case Western Reserve University who believes that gay marriage is a threat to heterosexual marriage, points out what he views as disabling difficulties in these efforts by Catholic scholars.

The premise of natural law is that it is "natural." That implies that thoughtful people, regardless of cultural or ethnic background, will form a consensus in support of the natural law principles. The concept of natural law is that it arises from humans' intrinsic moral principles. But humans overwhelmingly reject many of the principles of the purported natural law. Dent explains:

Although this doctrine is not overtly religious, all its leading proponents are Roman Catholics, and it contains elements that most Protestants and Jews reject, such as treating sex with contraception or any sexual act other than vaginal intercourse within marriage as immoral.

Catholics' actual sexual practices overwhelmingly reject many of the principles of the purported new natural law. Most Catholics masturbate, use contraceptives before and during marriage, engage in heterosexual sex prior to marriage, and engage in oral and digital sex before and during marriage. Virtually all Catholics engage in forbidden heterosexual sexual practices during their lives. They do not, as a group, display disabling guilt despite violating Church doctrine. Gay Catholics virtually all engage in homosexual sex. Dent concludes that the "new natural law" is "arbitrary" (its convoluted structure arises from the imperative of accommodating a Catholic doctrine that Dent finds incoherent). Dent finds that the new natural law is not new, natural, or a sound basis for law.
