So, Governor McGreevey knew exactly what he was doing when he announced, "I am a gay American." In addition to eliciting compassion, he was appealing to the double standard the country holds on behalf of gays -- and striking a blow for same-sex marriage. That is why, as the New York Times reported on its front page, McGreevey's "precisely worded bombshell line -- 'I am a gay American' -- was strategically devised with the help of a national gay rights organization the governor had consulted."

What makes the assertion even more manipulative is that it may not even be true.

The odds are that the governor is not homosexual but bisexual.

On the assumption that having been married twice he has had sex with at least two women, and on numerous occasions, it is quite likely that he was able to perform sexually with them -- presumably in a way that did not arouse their suspicions.

How is this to be explained? Aren't we repeatedly told by gay spokesmen that a homosexual man can no more enjoy sex with a woman than a heterosexual man can enjoy sex with a man?

Either this assertion is false or Governor McGreevey is not "a gay American."

The odds are therefore overwhelming that Governor McGreevey is a bisexual who prefers men.

But if he had announced he was bisexual, he would have received far less sympathy, because unlike homosexuals, bisexuals do have a choice.

We have come a long way from society unfairly condemning homosexuals' perennial fear of blackmail to a time when announcing one is a homosexual is a sympathy-gaining tactic.

And for those who believe that society unfairly pressures men to marry women, I suggest asking Mr. McGreevey this: "If you could do it all over again, would you have never made love to a woman, never married and never had the two daughters you have?"

Yes, society pressures men into marriage, and admittedly, some men, not only gays, should not marry. But without that pressure, far fewer men would marry. Just as McGreevey may have always preferred sex with men, most heterosexual men married to a woman would prefer sex with a succession of women to sex with only one. Marriage demands of all men that their sexual nature not be fully expressed. It does so for society's sake, for the sake of children, for women's sakes, and, yes, ultimately for men's sakes as well. Admittedly, such an idea is foreign to those who believe that sexual self-realization is the highest personal value.

No politician should have to resign from office because he committed an infidelity. But gay politicians should be held to the same standards as straight ones. Otherwise, "I am a gay American" will continue be a great defense, even when it may not even be true.
