[Moseley]

Apparently a lot of gays and lesbians haven't followed your abstract rules.

The abstract rules are the theory of evolution. The theory of evolution requires that homosexuality must be extinct by now -- if homosexuality is genetically based.

Therefore....

Homosexuality is NOT genetically based.

Homosexuality is uniform -- at a very, very low frequency -- throughout time, throughout geographic regions, throughout all ethnic groups...

... because it is development, not genetic.

[Albion Wilde]

Homosexuality is NOT genetically based.

That may be, but it's not because gays avoided marriage to the opposite sex or procreating thereby.
