It has existed since man stood upright and it will continue for as long as man exists. The great thing is that people like you care and will work to help society rid itself of this evil. Just need to be a realist and understand it will never be 100%.
No one blames whites for racism. Trust me, I'm black and I've grown up in a racist society and have been rejected by the community because of my race. It's not white people's fault alone it's humans. Some blacks are racist and some whites are racist as much as I hate to say it more whites are racist then blacks. I wish racism would stop but it's here to stay
