DWLs are not stupid or misinformed. They know that race exists. They know that racial differences are intractable because even they believe that heredity is the likely culprit. This is why these people are seemingly so impervious to rational arguments.
How do we explain the insanity of anti-racism then?
As Lindsay explains to Stark, it has a lot to do with the need to not be perceived as a Southerner, especially a low class White Southerner like a Scots-Irish redneck or a hillbilly who is prejudiced against blacks. Those people are “backward” and “ignorant.” They are not good liberals and enlightened progressives like us.
See, it is part of their ethnic identity: for many of these “Disingenuous White Liberals,” the essence of being a Yankee is not being a Southerner, which means not being a racist or a religious conservative. The White Southerner is “the Other.” We are their out-group. We are they to them.
Admitting that the South is right about the Black Undertow is not an argument that can be rationally weighed on its own merits. On the contrary, it is an existential challenge to the very core being of Yankeedom.
If the Southern redneck is smarter than the Harvard professor, what does that say about Yankee culture? If the South was right about African-Americans, what does that say about the last 150 years of American history? What does that say about the War Between the States and Reconstruction and the Civil Rights Movement?
How else can we explain the existence of Detroit and Philadelphia? The Whites who live in Michigan and Pennsylvania must be suffering from some kind of mass delusion - a delusional and idolatrous belief in equality – to tolerate the destruction of their own civilization by African barbarism.
