Can stereotyping be illegal

Yes it can be if it is used to discriminate against the person. An example would be a blond applying for a job and the employer doesn't hire her because he thinks blonds are dumb. This is stereotyping that has become discrimination. This often happens to people in several ways due to age, disability,race, and religion. With all of these things goes a stereotype. When discrimination happens because of these things it is against the civil rights act so it is illegal.
