The human race has been given a wonderful gift. We can logically determine how reproduction occurs and if it is correct for our situation. It is an animal mentality to feel the need to reproduce no matter what. 

It is true that some of the human race cannot naturally reproduce due to choice or biology. Who are dead ends with no rights? I guess I am. I have been heterosexually married for well over 10 years. But we never planned on children because it wasn't right for us, and then I experienced a form of cancer that made me sterile. So I never planned a reproductive lifestyle and am physically unable. I am a deviant. And proud.
