There are two fallacies about homosexuality that many sincere people believe. Here are some considerations for all fair-minded individuals to consider:

Logical fallacy 1: Many Christians Feel Homosexuality Is Against God’s Law.

  • This argument is based on faith. As the Bible says, “Faith is the substance of things hoped for, and evidence of things unseen.” (Hebrews 11:1). An article of faith purports to be a bit of knowledge that does not come through rational evidence. If something can be known from physical evidence and replicable experiment or logic based upon physical evidence, it can’t be faith. Those Christians who have been saying that homosexuality is a sin on this forum have quoted the Bible to prove their point. But their point cannot be accepted unless one unquestionably and uncritically accepts at least those verses as being the revealed word of God.
  • As a consequence, there has been a fair amount of heat between those who think homosexuality is some kind of sin because some verses in the Bible say so and those who don’t accept the validity of those verses. But there can never be a meeting of minds unless the believer is willing to accept as valid the mounting evidence that homosexuality is a natural human variant like left-handedness. Moreover, many animal species, including dogs, penguins, bonobo chimps, and sheep have members who practice homosexuality. Therefore, if God created these species, God must approve of this behavior in them. However, because most believers will accept faith over any evidence science can come up with, faith trumps reason and this argument does not convince them.
  • There are things in the Bible that no Christian on this board believes. For example, in Deuteronomy 21:18-21, the Bible says that if parents have a stubborn son, they should turn him over to the authorities to be stoned to death. In Leviticus, Chapter 19, Verse 19, it says that one should not plant two types of plants in a field, and one should not wear cloth woven of more than one type of thread. So a logical question to ask of these Christians who condemn homosexuality as being unbiblical is this: If one is not going to “pick and choose” which Bible verses to act upon or believe, why would you not turn your disobedient son over to the authorities for death by stoning or punish all those miscreants wearing Dacron-cotton overalls while they tend their organic farms that have a variety of plants?

Logical fallacy 2: The natural function of sex is procreation, and so homosexuality is a dangerous perversion of what is natural.

  • This also is fallacious because it assumes what it sets out to prove. That is known as a circular argument. One of the natural functions of sex is procreation, but very few believe that it is the only function. But to say that the only natural function of sex is procreation is quite different than saying one of the natural functions of sex is procreation. That is like saying the natural function of the tongue is to taste and so using it to speak is a perversion. To me it seems quite likely that sex also has a social and interpersonal function. We are social creatures, and the humans and bonobos are the only species whose females have the ability to enjoy sex. For both humans and bonobo chimps, sex plays an important role is social institutions, relationships, and loyalty. And homosexuality is widely practiced by the bonobos as noted above, even more than among humans. Therefore one cannot logically conclude that homosexuality is unnatural because it cannot lead to procreation, because this argument assumes that procreation is the only natural function of sex against much evidence to the contrary.
  • A sub corollary to this fallacy is the often-made statement that if all humans were to be homosexual, the human race would be extinguished, and so homosexuality must be a perversion. I have heard both Christians and Muslims say this. However, this is the famous slippery-slope fallacy. If all humans were to be stonemasons, the human race would die out too, because we would have no farmers or carpenters. If all humans were to be full-time musicians, we would all die out too. Human history shows that homosexuals are always a minority, as are left-handed people or people with eyes of different color, etc. And contrary to what many social conservatives think, the vast majority of homosexuals are not trying to “convert” anybody. As a matter of fact, I suspect that the ratio of heterosexuals trying to convert homosexuals is about a billion times greater than the number of homosexuals trying to convert heterosexuals. I don’t think you can find any homosexual web sites dedicated to converting heterosexuals. but you can find plenty of Christian web sites about converting homosexuals.
