Ironically I find this disrespectful toward women. It sort of implies that a childless woman is of lower stock, a "failed woman" so to speak and I reject the notion that motherhood (or fatherhood for that matter) increases the value and the virtue of a woman.
No, it implies no such thing. You are reading more into this than I described. Women who are not mothers have and earn my respect in the same way as all humanity and life.
