More important, also

Roughly speaking, there is some overlap between the cultures that practice child marriage and those that practice female abortion. I know the overlap is not complete; that Koreans practice the latter only and Arabs the former only. But that is not the case in the Subcontinent, where most child marriage and most female abortion happen. You would think that if girl welfare really was a goal, there should be at least the same focus on saving their lifestyle at 12 years than their lives at 12 weeks. Yet "women rights advocates" save all their rage against marrying girls and have nothing to say about killing girls. Sorry but that is not only hypocritical, but pretty much bares that the real issue they have is with the sex, not with girl welfare or rights. Same as, in other countries, "saving" girls from prostitution (or labor generally) is about keeping them dependent, not about improving their lives.

This need not even be an argument for child marriage, at that. In itself it isn't. It's only an argument against those who are fighting child marriage.
