From the time the 20th century began to the time it ended, so much has changed about how certain races are perceived, There are still things that should be changed, but america has come a long way with equal rights regarding race. Segregation laws that began in 1896 did not end until 1954 which was not very long ago. Not only did the law fail with the "separate but equal" saying, there were also literacy tests for African American voters that was extremely difficult to pass. Thankfully we do not have such laws anymore, but there are still active KKK members who do still hurt and discriminate people of color. A lot of African Americans are also still stereotyped as thieves, aggressive/dangerous, and even sometimes "dumb". So yes, there has been a lot of progress but there is still a lot that needs to be changed.
