I read that article you posted and one thing you fail to note, the zoo workers that noticed this found it odd that those same couples didn't have little penguins. It wasn't until they spent a lot of time trying things out that they figured out why, since penguins have no outword genetic signs. They then put those same penguins with ones of the opposite sex to change things.
My point is, doesn't mean that's right. The point in have a planet full of both male AND female species is for procreation. If homosexualty were the norm, then there would only be 1 gender on this planet, and it would have been wiped out once all of them died off.
So you've proven nothing by that statement.
It's a rented tux ok? I'm not going comando in another man's fatigues.
