I completely disagree with your saying that people can call you selfish! Deciding to not have children is not selfish, especially considering the strains humans are placing on our overpopulated planet. Also, nobody has a right to negatively label you. The number one cause of female poverty is motherhood. More people should acknowledge that fact. Those who choose not to have children should proudly take care of themselves and hold their heads high. I agree with your statement that selfishness is having children and then not showing up as the parent they need. I say this as a mother of three.
