One thing we know about homosexuality is that their selection is not biological. Because any trip down that lane is a genetic dead end as homosexuals do not pass their genes to their children.
Nope, its a choice. The only difference between man and animals is man has the power to make spiritual choices. Animals don’t.
Sow to your flesh reap of the flesh.
Biology is doing everything it can to destroy homosexuality, look at their average life span. Homosexuality is a 100 and 1 ways to die example.
Not necessarily.
Consider matrilocal societies, where the man goes to live with his wife's clan. Heterosexual boys do not contribute to their clan, because they will leave when it's time to get their own wives. Homosexual boys will tend to stay with the clan, and contribute to the survival of the clan, including the children of their sisters, who share much of their genes.
Matrilocal societies were pretty much superseded by patriarchal societies, where the woman would go live with her husband. At that point, the gay gene became much less useful.
***************************
Homosexuals are perfectly capable of producing children (and thus their genes), with each other or with a heterosexual. Our neighbors are lesbians. Prior to their meeting, one became pregnant with twins through a relationship with a man. It has not been unusual in the past and even now for a man to conceal being a homosexual, to marry, and to have children. At times men and women who have been homosexual have married each other in order to conceal their inclinations, and have had children together.
Despite all of this, homosexuals are still a small percentage of the population. What does this tell us? I believe it should be clear to anyone who is willing to see that homosexuality is an aberration.
