What is your opinion of women who say they do not want children, ever?

Whenever I tell people this, I hear some very rude and dismissive comments. “Oh, just wait till you’re older honey”, or “you’ll never know what its like to really love someone”. There are so many reasons not to want children, but most people do not want to hear why, they just want to tell me why there is something wrong with me. To add to this, why do people think just because they’ve procreated, they are somehow superior, or have more “moral sense” about the world? Shall I list off all of the horrible things parents do to their own children? I’m asking an honest question, I’m not trying to be rude!
