We know of black racists? We aware of white racists? And the opinions of both even if lost in myth and facts.
We know of Italians with bigoted views. But for whatever logic? Many are afraid to address the Jews. And yes, some of them are racist too. It's more than black and white issues in society.
We know of churches that preach love. And racist in the tone of many within the church. Which why many have lost some great leaders of the flock.
You can't preach love for one another. When you surrounded by a racist flock. Life, meant to learn, live and adapt.
God doesn't need to intervene between us to love. Just reading the trouble faced by the Almighty Jesus. He faces more and more harshly.
So racism more than between to groups. We see this daily as living proof.
