Racism should be gone for good because it has impacted our history in bad ways like making little black kids want to be white because they have learned that white people are the good ones and the colored ones are the mean bad one that hurt people.
In every history book they have told the side of the white people always being nice and the colored people being bad, but they have never told the side where colored people suffered because of their skin color or race. Slavery is an example they treated them poorly like animals selling them like they were nothing. Treating African Americans, Chinese, and Latinos just to name a few like trash beating them up getting disrespected because they were a certain race or skin color. They didn't get choose to be that way they get didn't choose what skin color they were or their race. Some people are racist they just learned how to hide it.
Well first of all, history books don't really side with the white man except in the instance of the conquistadors, they also side with the rich man consistently by classifying John Rockefeller as a "philanthropist," because of all the money he gave away, they leave out the part about how every cent he donated was blood money, and he was guilty of a massacre, look up "the Ludlow Massacre," it's like saying Adolf Hitler was a philanthropist because he fixed the German economy. This is a little off topic though.
Also, you didn't answer my question, how would you enforce a ban on racism?
