The thing is that I think the term came into use as somewhat of a backlash by those who are tired of having to explain over and over to the vast majority of people questioning them why someone might choose not to have kids and then being dismissed as anti-kid, abnormal or worse. I think once society gets to the point where the majority of people finally get that it is just a choice, and I believe we will get there eventually, it won't be as much an issue.
