Spoiler alert: no.

First, let’s define “natural.” Here’s what Merriam-Webster has to say:

• “being in accordance with or determined by nature”
• “having a specified character by nature”
• “occurring in conformity with the ordinary course of nature : not marvelous or supernatural”
• “existing in or produced by nature : not artificial”

For something to be “unnatural,” then, it would have to be the opposite of these things.

And now here are some facts about homosexuality:

• Same-sex attraction exists among humans all over the world.
• Although there’s no such thing as the “Gay Gene,” plenty of research has suggested that ties do exist between genetics and sexual orientation.
• While some research has shown that one’s environment can influence their sexual orientation–for instance, a study showed that gay men report less positive interactions with their fathers than straight men–such factors aren’t exactly up to the individual to choose. (Also, one can’t really determine causation in cases like that.)
• In general, psychological authorities agree that homosexuality is caused by an interaction of countless factors, usually develops in early childhood, and is not a choice.
• There is no evidence that sexual orientation can be forcibly changed through “conversion therapy” or any other methods. (However, one’s orientation may be fluid and can sometimes change on its own over time, just like other types of sexual preference.)
• Even animals can be gay! Homosexual behavior has been documented in tons of different animal species, such as penguins, pigeons, vultures, elephants, giraffes, dolphins, lizards, sheep, and, curiously, fruit flies and bedbugs. Bonobos, meanwhile, are almost entirely bisexual.

Compare this list to the definitions of “natural” above. Could it be that homosexuality is just a part of nature?

Some people like to claim that because homosexuality is “unnatural” because it’s maladaptive in terms of evolution–after all, how are you supposed to pass on your genes if you can’t have biological offspring?

First of all, for various reasons that I may elaborate in a future post, I don’t believe we need to let evolutionary concerns dictate our behavior. Second, there are plenty of other conditions that people are born with that aren’t evolutionarily adaptive–albinism, for instance. Nobody goes around railing about how albino people are “unnatural.” (Except perhaps in parts of Africa, where the condition is heavily stigmatized. But it goes without saying that what happens to albino people in some cultures is deplorable.)

That’s not even to mention the fact that, last I checked, it’s not anybody’s business whether or not particular individuals want to pass their genes on to the next generation or not.

The reason I’m writing about all of this is because homosexuality’s supposed “unnaturalness” is a common justification given by bigots for why they oppose gay rights. (For some examples, see here, here, and here.) As usual, however, their arguments have nothing to do with the meaning of the word “natural” or with current research on homosexuality. (At least among Christians, the idea that homosexuality is “unnatural” comes from bible verses such as Leviticus 18:22, which refers to same-sex relations as an “abomination.” There’s a vague line of reasoning if I ever heard one.)

Therefore, I wish they’d just give the real reason they don’t support gay rights–that they don’t like gay people, don’t wish to examine why they feel this way, and would rather the LGBT community just shut up and stop making their lives so difficult.
