Women who find males nurses unattractive simply find them unattractive and that is fine. Then there are women and men who look down on male nurses or would feel ashamed in front of friends if their husbands/familly started to work as nurses. That is different and unfair. Calling it sexism (or internalised sexism) is accurate.

There are women who believe that women are less capable in a lot of ways - and expect that from their own children. Partly it is what they internalized in childhood and partly because it can be convenient excuse.

Social value is based on attraction. If a woman feels ashamed of her husband being a nurse, it's because, since most people don't feel this is attractive, society doesn't feel it's attractive. She has chosen a partner that most women would reject as he has low income, making it hard to provide for her children, and is concerned with nurturing rather than competition, which is an undesirable trait for her male children to have.

There is absolutely nothing wrong with wanting a partner who has social value, and you have no right to shame anyone for their biological desires.

I didn't speak to misogyny.

Did make a status argument.

Your point on attraction has merit. I am not sure low attraction is the same as looking down on others.

It is not a stretch. Both men and women are complicit in reinforcing gender roles and perceptions.

Agreed
