Because that TOTALLY solved racism, right?
Government action, firstly, isn't going to solve the entire problem. Secondly, the government won't do shit if people are not behind it, regardless of the constitution. We saw that shit pretty clearly in every single minority discrimination and such.
Yeah, what Jumpluff said lol. If people still believe that you are less than a person, that's still a really big problem, even if you are a full person in the eyes of the law. The law is a good step but it's not the only thing.
