I'll subscribe to that idea, since our behaviors are largely dependent on our species being civilized, a burden of criteria other species don't have to meet. If a male dog sees a female dog in heat, the male dog naturally attempts to mate with the female... do we apply this same natural instinct to humans, making it quite acceptable to rape women? No... we establish guidelines of behavior (laws) where we are expected, as a civilized species, to adhere to. If I am a hungry dog, and another dog has a big bowl of food, my natural instinct is to take the food for myself if I can... should this apply to people? Okay... one more... If I am a dog at your sister's wedding, and my balls itch, I might just start licking them right there in front of the preacher and guests.... should this same standard apply to people? ....I mean, other than in YOUR family?
