Ah, but, Bagpuss, don't ya know, if society is prejudiced against children whose parents are of some minority - such as mixed race couples - those kids will be MADE FUN OF.   And we all know nobody who's seriously picked on as a kid EVER grows up to make anything of himself or herself!    So, as long as society makes fun of homosexuals or looks down on them, it's child abuse in and of itself whenever gays or lesbians raise children. Even their biological offspring.

QED

Those kids should be raised in a loving, nurturing, stable FOSTER HOME.
Or series thereof.
