Looks like a slight error; the phrase “male chauvinism” might be what was meant.
“Male chauvanism” is what was meant. I grant that chauvanism is not limited to gender. Although I don’t think many would confuse her for meaning excesive patriotism if she called him merely a chauvanist. It would be like wondering what empire Mitt Romney was in favor of after Castro called him an imperialist. It’s understood.
