The people who protest too much are the ones most likely to make stories for the EMTs to laugh about later on. Or they wind up being caught buggering children. A lot of them already do and are conflicted about it, and those are usually the worst kind, wanting to make a particular act a felony or even the death penalty. When they want that you can be pretty sure that there are mutilated cat and dog corpses buried in their backyard.
That's nice, but my problem is with your usage of the words "too much". Contrary to what you believe, I do not protest beastiality a lot. In fact, this is the first time I've ever said what I think about sex with animals without being asked directly for my opinion. If someone mentions the topic and wants my perspective, I'll tell them. No vociferous protesting from me, son.
So you might be lucky enough not to be like that, but you could be said to have the tendency. An unnatural revulsion or hatred towards something is just as much an attraction as an all-out sexual desire that compels you to tell your buddies that that sheep really has a nice ass.
So now, on top of the imaginary "gay gene", some of us have a "beastiality gene"? It is sickeningly amusing how far some of us will go to defend our actions. You blame genetics to compel you towards doing something you know is wrong because you're too weak to stop yourself. Truly pathetic.
