I don't think it's ignorant, I think it's a noble standard to strive for.Which is obviously ignorant since we know tribalism is a hallmark of heterogenous societies. It doesn’t sound nice and PC though so I get why people cling to the axiom. Beats pointing out hard truths
Remember, many factors which plague today's modern black culture weren't always so. Black culture used to produce beautiful classy jazz, now it pumps out toxic ghetto rap reflecting the drug, gang lifestyle.
So race isn't the problem, it's certain cultures based on certain values.
