Nope. Not a choice either. Research has shown evidence that there are certain genes that can make a person homosexual. Basically, a gay gene or even genes exist. Gender and sex evolutionized to be different. Gender is determined on how one acts or dresses then sex is determined through the genitals.
So being gay is a genetic defect then? If so, why aren't we trying to cure it? I'd be willing to donate money to fund research to find out more about it and find a cure for the genetic defect if that was the case.
In either case, being
openly gay is a choice.
It can't be the same though, since people clearly stated that they do not identify as male or female.
That's just what they claim. Just because someone doesn't fit the stereotype for their biological gender doesn't mean that they don't identify as a male or female.
