Actually, we were talking about the belief that a person chooses to be homosexual for selfish reasons. I’ve already pointed out that this “choice” causes more difficulty for a person than either A) choosing to go with the majority and be heterosexual or B) choosing not to fight their innate heterosexuality, whichever you think is the alternative, and thus is unlikely to be the selfish choice.
It seems to me that choosing heterosexuality, were it possible, might be considered to be the more “selfish” alternative because it results in so much more benefit to the person. Among these are approval from family and others, a scaffold of laws giving certain benefits to heterosexual marriage allowing one to avoid wills and powers of attorney if desired, an abundance of possible life partners (about half of the single adult population), and the usual sexual gratification that will go along with one’s chosen sexual orientation.
However, I think it is silly to call either alternative selfish or unselfish. People simply make the best of their situation, whether lucky (heterosexual) or unlucky (homosexual) in their genetic and environmental lot.
