It is still an attempt to stretch data to fit a hypothesis. How is the homosexuality passed on since natural selection is not selecting for it?
Group selection is one of the basic concepts of evolution. This is by no means an unusual "stretching of data."
A study has shown that in humans, women with gay brothers produce more offspring than women with straight brothers or no brothers. The reason for this is unknown, but it is likely that it is due to a genetic tendency for greater fertility in women that also causes some males to be gay. This is a selection pressure. Now, if the gay males furthermore provide better child care, the genes of their parents will be passed on at a higher rate. Their DNA specifically is not passed on, but the genes from their parents are, including the genes that caused them to be gay.
