Actually, the “science is settled” regarding biological origins of homosexuality. The results have been buried by the pro-homosexual media, but they stand nonetheless.
It comes from studies of separated identical twins. If it was biological, there would be a much higher incidence of homosexuality among separated identical twins, but there is not.
Ooops. Never mind. Put the studies into the memory hole and never mention them.
Souls and environmental spiritual factors appear to dominate the picture. That is exactly what you would expect if the bible were true.
The bible acknowledges the phenomenon of being born in sin. This is on individual basis. Family curses are also a phenomenon known in the bible.
Put in mind that regardless of what causes the attraction, the behavior is separate from the attraction. It’s like telling the Hawaiian or Native American people to give up on life because their genes made them addicted to booze.
