noun (m)
(male) chauvinism
+ masclista
adj.
chauvinistic
noun (m)
(male) chauvinist (pig)
I note that this latter noun is marked as (m / f) in the GDLC. I'm not sure what you would call a woman who supports the theory that men are superior to women - other than an 'idiot'.
That the word "masclista" noun (f) exists does not entail that the concept is instantiated in the real world
What's wrong with "No hi ha cap dona que sigui masclista"?
