My only quibble with this article is that the fact that there is a wall related to child bearing and rearing IS institutional sexism.

It's just a different form of it than the "my coworkers constantly stare at my tits and don't take what I say seriously" variety.

We've put women largely in charge of child rearing duties. Obviously, men aren't able to get pregnant and bear children. We are, however, perfectly capable of changing diapers, singing lullabies, and doing laundry.

I'd bet that we would see the same kind of impediments to women rising to the tops of their professions in many demanding fields, fields where if you take too much time to have a life, you are considered broken and uninterested in excellence.
