Stereotyping means having a fixed idea about what a particular type of person is like, especially an idea that is wrong.
Stereotyping can make people feel bad or not treated fairly. It can make people feel like they are not seen for who they really are.
Examples:
Stereotyping is when people think all girls like pink.
He is stereotyping by thinking all tall people are good at basketball.
She doesn't like it when people are stereotyping.
We are stereotyping if we think all cats are mean.
Stereotyping is when people think all old people are grumpy.
Stop stereotyping people based on how they look!
