Betrayal
I have tried to pin down that feeling that one gets when they first confront the seemingly bizarre reason that humanity is such a mess.
In retrospect, I realize I had the same feeling when I first realized what was wrong with humanity. Maybe the biggest difference is that I had already been looking for what is wrong with humanity. Even so, it still dogged my steps for the last fifteen years. To utter a word about the lack inherent in the animal's rutting rendition of coitus felt like a betrayal. It is only a betrayal of the animal which, it ends up, is required in order to release our Humanity.
