Spot-on re: the lack of assimilation leading to/causing lack of trust.
Mostly homogenous societies don’t have race hustlers like Al Sharpton and Jesse Jackson, or race baiting politicians like (enter any Democrat here).
There’s “diversity” and there’s “division”....you are correct, Jesse Jackson and Al Sharpton are DIVIDERS....and you don’t see their kind in England, Russia, Germany, even Canada.
