Stereotyping is to believe, think and say groups of people are the same even when they are not. It is an unfair way of judging a person.
An example is Asians are bad drivers. I disagree because a lot of Asians can be good drivers.
Another example is smart people wear glasses. I disagree because a lot of people don’t wear glasses and they are smart.
Overall, stereotyping is an unfair way to judge people because of their culture and beliefs. It can hurt people on the inside.
