Wouldn’t being born gay mean nature selected you to NOT be a parent though?

The natural selection part happens if you don't reproduce because of being gay. The gayness itself is just a random mutation. 

If the rules change such that being gay is no longer an obstacle to reproduction (i.e. surrogacy becomes popular, etc.) then being gay will not be naturally selected out of the population.

This is all assuming that sexuality is genetic, which doesn't sound right to me, but I can't say.
