Some heterosexual couples can't procreate either. And gay people care just as much about their spouses and are just as proud of them as straight people are. But they you get to the heart of your argument--that homosexual relationships are "aberrant behavior." I disagree. Gays and lesbians are a minority, but that does not make them aberrant or sick, and major mental health organizations agree. I also happen to know some who are wonderful parents. But at least you're being honest--the argument is about the fact that one side sees gay people as aberrant, the other as a perfectly normal variation within the realm of human sexuality.
