Gawd, thus is arrogant nonsense.
Wilkerson clearly articulated in her book that the grievances of the "angry whites" are real snd legitimate.
What she is analyzing is how these grievances and the underlying causes giving rise are being wrenched and shunted into a perceived threat to tribal/caste group self-definitions -- and thereby becoming weakness oriented and possible to solve.
Your screed, Jim, would fit quite nicely into "We whites] are bring replaced" by the threats to our racially defined caste/tribe.
Which is just the kind of caste/tribal misdirection process that robs those in crisis from any real ability to solve the real underlying problems.
But pretending that our culture and polity does not define itself in racial caste/tribal terms is to ignore facts on the ground, rob the dispossessed of political allies and power, distract those in crisis into false and even silly gamesmanship, and thereby preserve the hidden power of the few.
For decades, another perceived threat to the U.S. power structure were those Micks and/or those wops.
Now no one really thinks about these tribal definitions.
But Colored/Black/Brown definitions government vast ramifications in our polity and culture -- as they have since the days when all 13 Colonies had slavery.
And the fact that on the whole these tribal definitions have been willy nilly converted into castes still plagues our polity.
Refusing to admit these facts -- and resorting to the most ignorant name-calling as you have done, Jim -- simply preserves the inequities our caste system fosters.
