The second sentence makes as little sense as the first: “That’s why most of the medical (not socio-spiritual) blame for today’s rise in homosexuality must fall upon the rise in soy formula and other soy products.”
Has there been “a rise in homosexuality”? If so, Mr. Rutz seems to be the only one who knows about it. What there has been is a rise in the number of people who refuse to live their lives “in the closet.” Most leave the closet willingly, but some – such as antigay evangelicals Ted Haggard and Paul Barnes – need a little push.

Mr. Rutz wants – indeed needs – something to “blame” for homosexuality. How ironic that one who claims to be preaching “God’s truth” can’t find it within himself to accept “God’s plan” as evidenced throughout human history.

Homosexuals have existed in all cultures and in all times, even before soy milk and tofu were invented or consumed. From prehistoric rock paintings left by the San people in modern day Zimbabwe, to ancient Greece and Rome and the “homosexual” Christian saints of the Middle Ages who left a considerable body of love poetry dedicated to their partners:

He was the refuge of my spirit, the sweet solace of my griefs, whose heart of love received me when fatigued by labors, whose counsel refreshed me when plunged in sadness and grief... What more is there, then, that I can say? Was it not a foretaste of blessedness thus to love and thus to be loved?

– Saint Aelred, from his eulogy for his lover Simon

...to Native American berdache who were venerated for their “two-spirit” nature, homosexuals have always been present. One would naturally conclude, therefore, that homosexuality is part of “God’s plan” and the specific nature the Divine ordained for some individuals.

Blind to history, Rutz continued his apologia by claiming that women who give soy milk to their babies are turning them into future homosexuals because of the estrogen content of soy. He proclaimed that “most babies are bottle-fed during some part of their infancy, and one-fourth of them are getting soy milk!” If one-fourth get soy milk, using Rutz’s “reasoning” shouldn’t one-fourth of the population be gay?

Not surprisingly, Mr. Rutz offered no studies to support his “medical” claims about the effects of soy on human sexuality and men’s penis size. Could that be because there aren’t any?

Reality check. A part of the gay community as well as an ever-increasing part of the straight community are vegetarian or vegan, which means they consume a lot of soy products including the dreaded tofu.

Common sense. If, as Mr. Rutz claimed, soy “commonly” leads to a decrease in penis size, don’t you think the diligently voyeuristic media would have picked up on the worldwide stampede of men seeking medical help for their shriveling penises?

Undaunted by reality and common sense, Mr. Rutz continued his argument providing a telling look at its motives:

Homosexuals often argue that their homosexuality is inborn because “I can’t remember a time when I wasn't homosexual.” No, homosexuality is always deviant. But now many of them can truthfully say that they can't remember a time when excess estrogen wasn’t influencing them. [italics added]

This sounds a lot like what the defenders of slavery and segregation once said: doesn’t matter if they were “born that way,” they’re still inferior and, therefore, “deviant.” Rutz should have a look at “When religion loses its credibility,” a USA Today article by Christian writer Oliver Thomas:

What if Christian leaders are wrong about homosexuality? I suppose, much as a newspaper maintains its credibility by setting the record straight, church leaders would need to do the same:

Correction: Despite what you might have read, heard or been taught throughout your churchgoing life, homosexuality is, in fact, determined at birth and is not to be condemned by God's followers. …

Christianity is in danger of squandering its moral authority by continuing its pattern of discrimination against gays and lesbians in the face of mounting scientific evidence that sexual orientation has little or nothing to do with choice. To the contrary, whether sexual orientation arises as a result of the mother’s hormones or the child’s brain structure or DNA, it is almost certainly an accident of birth. The point is this: Without choice, there can be no moral culpability. [link added]

What there is, however, are self-serving “moralists” who concoct new, ever more bizarre ways to demean and degrade their fellow human beings while hiding behind “religion” and scare tactics like “soy is feminizing, and commonly leads to a decrease in the size of the penis, sexual confusion and homosexuality.”

Morality is simply the attitude we adopt towards people we personally dislike.
