A most interesting point. Given the demographic mess of Communist China's "one-child policy" which carried on for decades, there are tens of millions males who cannot be matched with females.
Many cultures and many ideologies of the world have a long way to go before they can be fully considered 'civilized.'
Yes, the fact that one could only have one child, and the preference for sons no doubt has led to a lot of abortions in recent times, and probably to infanticede of females in the early days of Mao. I think of my mother’s parents who tried 5 times for a son until the sixth was a “success”.
