sexist

Unfairly discriminatory against one sex in favour of the other.

• [Sokka (Jack DeSena):] I knew I should've left you home. Leave it to a girl to screw things up. [Katara (Mae Whitman):] You are the most sexist, immature, nutbrained—I'm embarrassed to be related to you!
• What was all that about? Well, like all women, she's shoe-mad. 't's a bit sexist, isn't it? Do you know one woman who isn't obsessed with shoes? No, but I only know one woman. And she just left the room shouting "THE SHOES!"

A person who discriminates on grounds of sex; someone who practises sexism.

• I don't blame racists, sexists, lookists, or any other “ists” for what they personify and perpetuate. They are mere hostages of their egos.
• Narrators demonstrated resistance coping techniques through direct confrontation with aggressors, such as racists, sexists, homophobes, elitists, and misogynoirists.
