"To all the people calling these folks "selfish":
Do you think married people who don't want children should have them???
Stop and think for a moment."
And do you really think that the only reason someone doesn't have kids is selfishness? Unless you have quotes straight from that person like those in the article, you can't know why someone is childless and cannot assume a selfish motive.
Not at all! I think often it is very unselfish to not have kids. My argument is with those who look at this and immediately apply the "selfish" label.
