As a society, it is mentioned all the time. By pundits for political or cultural war reasons. Or inside articles about family. Or in articles about women health, or babies conception. In discussion about demographics. In discussion forums like this. It is talked about casually whenever any surrounding topic is talked about. Even reddit threads about relationship problems have that mentioned often. It is just not a secret.

If you never cared about family planning or female health, you never seen it. Arstechnika, the verge or gamera sites never writes about that. But it is not society not taking about it.
