It’s thinking that someone is inferior because of their gender.

For example, that girls are bad at soccer just because they are… girls.

But being good at soccer has nothing to do with being a girl or a boy!

Sexism is not new. In the Middle Ages, forbidding women to govern was ALREADY sexism!

But then, is sexism just for girls?

No, it also affects boys. But girls are still the main victims.
