Parents teach their children of racism and to be racism. The parent who tells a black child "no white person is EVER gonna look at you the same" is committing child abuse. It is generational and will never "end" until the parents stop indocrinating their children in division and hate.
I can’t say I agree with you there. If I had a daughter I would clearly tell her that the chances of winding up a single mother are extremely high if she dates black men, and I would clearly tell her that I don’t want that future for her.
