Some scientists say there's a genetic advantage to having the gay gene in a family line (not individual but family line). They are saying that if there's some survival advantage to the hetero (therefore reproducing) members of the family line, the gay gene would "piggyback" along the family line even if it produces nonreproducing members.
Also, the social stigma that accompanied homosexuality historically assured that the gay gene was passed on by otherwise gay people who were forced by society to act straight (aka get married and have kids)
