Try “chauvinism.”

"Exaggerated or bellicose patriotism" How is that relevant?

[Olog-hai]

Looks like a slight error; the phrase “male chauvinism” might be what was meant.

[Tublecane]

“Exagerrated or bellicose patriotism”

That is the primary definition, but I can’t imagine any current dictionary omitting zealous partisanship for some particular group to which you belong, especially your sex.
