Absolutely, a recent recording of an iTunes U course had a professor commenting on the projection of homosexuality in ancient scripts where a Roman Emperor had an appreciation for a male individual. The professor noted that a number of professors wanted to label the relationship homosexual, but he disagreed and noted that other types of relationships exist.

That being said, Hans Hermann von Katte and Friedrich the 2nd were lovers.

Surely it's simply a rebuttal to people who argue against homosexuality, and gay people, by claiming same-sex behaviour is "unnatural" and that animals don't exhibit it. (A recent example being Manny Pacquiao, which may have influenced the timing of this article.)

Attempts from both sides of the argument are politicized and misguided. There's no need to argue from the standpoint that "animals do it/ don't do it." There are plenty of things animals do that we don't. We're not animals and we should leave the poor animals out of our politics.

I want a variety of options for dealing with people who aren't persuaded by "why do you even care though" or "love is love."
