Also today I honestly doubt nurses are seen in any of those demeaning ways that you quote - men included. I don't society sees caretaking or humanitarian work in a demeaning way. But that's just MHO.
Men not filling up nurse jobs might not always be due to demeaning views of the profession, but also to not feeling fit for it, purely and simply. I support women emancipation and freedom, but we should try to avoid falling into misandry. Free at last! Free at last! Thank God Almighty, we are free at last! (Martin Luther King)
