A wave that moves up and down.
Whoa, this is a super interesting question! Alright, so I think we have definitely made progress. Since the Jim Crow era, segregation has been made completely illegal in the southern part of the U.S. and across the country. When you compare race relations to the Jim Crow era to race relations in the 2010s, we have <em>definitely </em>come a long way. However, that's not to say that racism and discrimination doesn't exist -- because it obviously still does in our society today. And honestly, I don't believe it will ever go away. Many forms of discrimination exists in the U.S. today, whether it's religious discrimination (hate crimes against Muslims and/or Jews), LGBT discrimination, and of course, racial discrimination (police brutality, etc.) Though I do believe we have made a lot of progress, it's not enough, and there are still many things that need to change.
