That's the point I'm making. That group of people, as you defined above, doesn't exist. Simply, if you don't view the homosexual act as perverted then you are a homosexual. Whether or not you have actually engaged in the homosexual act is irrelevant. So, if we ever do reach a society that has no concept or understanding of "homosexuality", every there would, by your definition (which I'd still like to see a link for, or for you to use another word than definition), be a homosexual?
A child, who has no concept of sex, yet alone homosexuality, and therefore does not view the homosexual act as perverted, is therefore homosexual?
By your "definition", every baby is therefore born into this world homosexual. I have to say, that concept disturbs me, and I reject your definition.
Please work harder at your definition ...
Sexuality, in human development, is influenced both genetically and socially. Homosexuals are born with a curtain proclivities, similar to the way an alcoholic may have a weakness. But as a society, we don't encourage alcoholism and we shouldn't encourage homosexuality. Like alcoholism, homosexuality is a destructive behavior for the individual and society as a whole.
