I was raised to always double down on an unpopular idea if I think there's something to it, so here goes:

From the point of view of genetic fitness, homosexuality is not adaptive. So you would think that the genes that contribute to homosexuality would be powerfully selected against, since the number of expected offspring from same sex intercourse is zero.

Yet gay people make up a sizable portion of the population, which is not at all what you would expect. Unless there is some mechanism by which homosexuals have historically had children despite their natural inclinations.

Given that some portion of anti-gay attitudes seem to be oriented toward getting them to "be more straight" (or whatever), it seems possible to me that homophobia (or at least a certain flavor of it) is an adaptation whose purpose is to get family members to pressure a gay person into having offspring, since they would have a genetic interest in those offspring.

But that is an argument about why a certain behavior might exist in humanity. It is not an argument that homophobia is okay or justified. It is not okay.
