Whether it’s Macklemore’s “Same Love” or Lady Gaga’s “Born This Way,” our culture is pretty convinced that homosexuality is inherent from birth.

But as it turns out, those within the LGBT movement aren’t that convinced themselves.

In an article in the Daily Caller, gay writer David Benkof presents the solid case of the historians—several of whom are also LGBT—who maintain that the sexual orientation of homosexuality didn’t exist until about 150 years ago.

While same-sex relationships and behavior have happened from time to time throughout history, LGBT scholarly studies show zero evidence of any culture with gay-oriented individuals at any point in history.

The mountain of scholarly research also continues to show no “gay gene” accounting for sexual orientation from birth.

The basis of these claims is that sexual orientation, as part of a person’s identity, is entirely a modern invention. Even in Greek culture, where homosexual behavior is known to have occurred, the line of reasoning goes, there is nothing to show that even a minority of individuals identified as gay or homosexual in any way. Rather, homosexuality was supposedly considered a supplement to one’s regular heterosexual relationships.
