The gay community appears to be playing down the genetic
concept, since some have speculated that all we gotta do
is shut down the gene that is coding for this behaviour
at birth...that kind of determinism scares the "free" and
"unfettered" hypocrites, who only use genetic determinism
as the truth when it serves in justifying their own appetites.
