You're simply wrong. My mother worked in the medical field for years. I saw plenty of male nurses emerging during that time.Male nurses do exist-- I never said they didn't-- but they are quite rare.
Just like men I know who are artists, designers, writers, and are bad at math. Go figure.What about if women don't go into certain fields because they don't like them-- personal choice perhaps?
Alas, we see only what we want to see....
Saying this doesn't make it so, plus it alleviates any responsibility for stepping in the other person's shoes and making at least a faint attempt to see the subject from another point of view.
