This is because women remain looked down upon.

(Unacceptable, but a disturbing reality today)

A woman presenting up, masculine is seen as tough, bold, generally positive terms.

A man, doing anything feminine, is presenting down.

Of course, all of that is silly, rooted in cultural norms too.

We have a lot of work to do before people get past this sorry state of affairs.

People should do what they can and feel good doing.

I think it's because people find certain roles more attractive. Men doing physical work, women doing nurturing roles are found attractive by more of the population.

I think that the women who find males nurses unattractive simply find them unattractive, rather than looking down upon their own gender. It seems a bit of a stretch and a really nasty thing to claim that these women have internalised misogyny.

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
