Puzzle no more Steve,the long, weary and unfulfilled search for a genetic link, is simply an attempt to validate homosexual behaviour,

"Validate behaviour"?? In whose eyes?

to prove that homosexuals are indeed, a different third sex of humanity.

Well that's a novel way of putting it. A "third sex" eh? Where d'you get this from, or is it an ake original?

homosexuality would be just another minority sexual behaviour, like incest.

Smear, smear, smear. Shame on you!
