One of the strange things about ridiculous sexist nonsense is that, because there's so much of it around and there always has been, it so often escapes our notice. We're used to things just being the way they are, until somebody brings it to our attention, and we recognize the nonsense for what it is.
Case in point: why do healthcare companies treat "women's healthcare" like it's some kind of add-on to "regular" healthcare? Half of the people in the world are women, and healthcare that is necessary for half of the people in the world is just "healthcare." It's not a specialty product: it's a basic human right. Even if it involves our woman parts.
