re: If homosexuals are “born that way”

There are some rare combinations out there too. I was originally the 3rd from youngest out of the 1st cousin generation. Now due to my 4 months younger cousin dying a couple years ago from a one off rare genetic combination, I am 2nd from youngest.

His genetic combination is a known rarity (I forget the name of the condition) that usually kills, by stroke, in the late 30's to mid 40's. He made it to just short of 55 with no idea he had it until it hit. We still have no idea which side of the family contributed to what either as his eldest brother, the dentist, subsequently paid for everyone in their family (down to Aunt's great grandchildren) to get tested for it. Deceased cousin is the only one with a trace of it at all. No others in the 1st cousin generation have even had strokes, heart attacks; yes, strokes; nada.

So I can envision a rare genetic combo causing 3% or fewer adults to be homo. However, I have yet to see the gene combo identified, or even hinted at. So yeah, "skeptic" (as in laughingly doubtful) present and accounted for.
