I have to ask bamnation, in all seriousness, dude, are you brain dead? I really dont mean to be insulting, but really??? Lets face a fact or two here. you place gay and lesbian (confirmed) people on an island, and you expect children...really? Have the words confirmed gay and lesbian been lost on you? Dont you think that the reason its not gene based or hereditary is because which of your two mommies or two daddies did you get this passed on from? This being the case, this would be bred out of the gene pool real fast. If your arguement was for chioce, I might concede some small point.
