Women Who Have No Kids and Dont Want Any?

Ok this is my first topic posted. I was reading the sinlge mothers thread and I had to ask a question:

What about women who have no kids and don't want to ever have any? Do you look down on them? Are they selfish/smart? Or maybe you feel like its their choice? Tell me your thoughts.......and yes I have no kids and I don't ever want any! Lol
