Urban Dictionary defines your definition as derogatory, and thus inflamatory in this context. The term assumes motives and misperceives shortcomings behind those who have children.

It would be akin to me calling a woman without children "barren", or assuming that she is childless purely because no man would want her to bear his children. Neither necessarily may be the case, both are inflamatory, both make unwarranted assumptions, and both insult.

Not having children was your choice. The rest of us need not be punished for it. An educated society benefits all.

In short, this is a diverse group of people, so, respectfully, please choose your words more carefully in the future.
