Answer:
Racism is an important topic, yet some people don't even know what it is. Most times when racism is pointed out, for example, at school, its not actually racism. Racism is a mix of someone or multiple people who think that one race it better than another or, that one race should be treated differently than another.
Racism has changed from based to better over the years but it is still a problem. Martin Luther King, made a big impact on that, with his I have a dream speech. It was important because he was trying to say that segregation and racism was wrong and should not be going on.
