I automatically think that the color of racism is white. Is that right/wrong? Are people of color as racist as whites? What color targets?

I think that white racism has a higher profile, certainly among countries that are predominantly or traditionally predominantly white...  We discuss white racism because that's the kind we see more of.. But yes, there is racism by non-whites, i.e. Asians hating black people... 

I knew someone who was originally from Pakistan - he hated black people, hated Chinese, hated Indians... and indeed most other nations and races...
