Racism will never truly "end" as it is an ugly part of human nature. It is easy for one person to discriminate against people based on perceived links between unrelated traits and actions. You can fight this as much as you want, but ultimately you will ALWAYS discriminate against many different things in your mind, race being one of them.

What drives racism to be more prevalent is division, segregation, making it very evident that there is a difference between a white person and a black person. That division is reinforced by many different things: media, music, upbringing, role models, vocal racists, vocal "civil rights supporters" (see: Al Sharpton, Jesse Jackson)... Black History Month is one of those things. The more society perceives a division between races, the more racist everything and everyone is.

When do you ever hear about black inventors outside of Black History Month? Are their contributions to society only important in February? I can tell you I sure as hell never heard a peep about them outside of BHM, and that is the damage that BHM does. Black inventors are no longer "people who invented things" but are now "black people who invented things. It dehumanizes them and makes their inventions somehow less important. It makes you mentally segregate them from other scientists, judges, senators, etc. I argue that this is the biggest form of racism today because it is most prevalent and makes a fertile breeding ground for the level of discrimination and hatred that we normally call racism: hiring practices based on race, stereotyping, even violence.

The less we make a big deal about race the more those lines, those divisions disintegrate. The harder it is to see the lines in the sand, the easier it is to notice that someone is discriminating against someone else.

tl;dr: Morgan Freeman looks like Nelson Mandela. Or, is it Nelson Mandela that looks like Morgan Freeman? I believe what we have here, gentlemen, is a conundrum. ಠ_ರೃ
