I disagree with this so much it is not even funny. while I realize many of the activists just use surrogates, the majority of homosexuals I know actually do have offspring that were conceived in the normal manner. They "became" homosexual after the fact. Often MANY, MANY years later.
And there's the rub... sexuality is fluid. Sexuality can flow from heterosexual to homosexual as we see so often, and from homosexual to heterosexual, as we see in the growing number of former homosexuals.
"..their type of relationship and denying the abnormality of it, including the inability to produce children. "
I don't think anybody said that homosexuals can't produce children. To be accurate, homosexual COUPLES can't produce children. Homosexual RELATIONSHIPS can't produce children. Homosexual INTERCOURSE can't produce children. Due to the reproductiv e structure of our species.
