Last time I checked, the activities you listed weren't sexual.
This likely comes as a great shock to you, but heterosexual activity has something to do with the reproduction of the species. Maybe you're in love with your lawn mower, but the last time I checked mine, it wasn't a sexual entity.
A man and a woman together can create a baby. Two homosexuals engaging in homosexual acts can't. Oh, homos can reproduce, but only by engaging in heterosexuality. In addition, homosexual acts are play-acted heterosexuality. One plays the boy and one plays the girl. Only it's not the real thing. It's not the normal thing. A male anus is not designed to receive a penis, and there's nothing up in there that can reproduce human life. Homosexuals know that their activities are unnatural and perverted, and they take out their frustrations by peddling their ugly deviancy to kids, which they can never produce by their own behavior.
That's something I wouldn't have had to explain if we still lived in a sane era.
No need to drag anii into it. I know two dykes who between themselves, a turkey baster, and some sperm managed to produce a baby in one of them. Was this a heterosexual act, homosexual or akin to mowing the lawn?
