Yep. And calling it "benevolent sexism" is absurd. By that same logic the bias that "men are smarter than women" is benevolent sexism.
I don't see the logic there.
The "benevolent sexism" is in regards to equating women with "nurturing" characteristics (in this specific case, that's not the only example). My poor understanding of the subject is that the problem is that you are then saying that woman need to be nurturing or they are failing somehow or not meeting expectations, whereas you might not place the same expectation on a man. And that this expectation should guide the roles and opportunities women receive. But it isn't used as a put down against men, just that people don't have the same expectation that men need to be nurturing.
The stance "men are smarter than women" is just plain old sexism since the statement can easily be written as "women are dumber than men".
