Racism exists, always has, always will. To ignore that is to do a great disservice to people. Racism is not only perpetuated by white people I might add. I suspect you will find some racists in every race, because racism is a form of ignorance, and that is rampant everywhere it seems at times. Sensationalizing racism is no better. We need to address it as rational adults, but we can't do that because the media want's to "stir the pot" not provide a platform to seek solutions.
I think instead of making it a "race thing" or pitting white against black, we all need to sit down and figure out what has gone so horribly wrong in our society that it has led to the problems we see today with violence, lack of personal accountability, education that is progressively slipping, and a for profit prison system that incarcerates large numbers of people. (we have 1/5th of the world's population and 25% of the prisoners - there's a systemic issue here) So many things we need to address that fuel this - but instead of the real problems we look at a handful of white supremacist idiots or want to rip down a flag as though that will obliterate the problems.
