Progressive Equality?

As a white American I understand that prejudice does exist. There are stupid white people torturing other races. How can the white American public who has no prejudice help to stop it? I read about a black woman lured into a white trash mobile home/shed where she was tortured and abused for days. I am sickened that people do these things to other people just because the color of their skin and for their own sick reasons. Could it ever be possible for all of us to unite and have progressive equality? Kind of a leave it all in the past and move forward way of thinking or are things just that bad in this county? Can it be fixed or are we going to continue hurting each other? I've had the mindset of "I don't hurt people so it doesn't exist" but it does and I want it to stop. I wish us whites could stop being stupid and the blacks could stop thinking we hate them and all other races could just be accepted as well. Why do we have to separate humans by color? Is there any hope?
