From time to time, I hear people informing me that homosexuality as a lifestyle is morally acceptable “because people are born that way.” In other words, being born with a genetic predisposition to a behavior makes that behavior “natural” and is therefore seen as a moral defense. In spiritualized terms we hear this expressed as “God made me this way so it must be ok.”
For starters, a biological cause of homosexuality is merely a theory; science has not at any point isolated a “gay gene.” Now to be sure the human genome is an incredibly large and complex thing and just because we haven’t found it yet doesn’t mean one doesn’t exist. But nonetheless, when people speak about people being “born gay” they are speaking with a certainty that hard science does not currently support.
But let us assume for argument’s sake that we do at some point isolate a gene which predisposes people to experience same-sex attraction. What does that mean? A person may be genetically predisposed to all kinds of things which are completely unacceptable by most moral codes and society in general. For example, a person may have a genetic flaw which makes them more susceptible to alcoholism, sociopathic tendencies, or other forms of mental illness. Are we then to embrace the alcoholic and the sociopath and tell them that their behavior is perfectly healthy because their genes make them do it? Drink up! Stab your mom! God made you that way so it’s ok!
The same problem exists when we hear arguments justifying homosexuality because it exists in nature between various animal species. It undeniably does. But then again so does incest, fratricide, and cannibalism — all practiced with impunity and complete lack of moral judgment. If we are mere animals then morality is of no consequence to us.
The argument surrounding homosexual behavior and human sexuality in general is a complex one. However, the argument that something is permissible because it is biologically determined is a non-starter.
