Source: The Original Sin
The original sin of modern conservatism is that it never came to terms with the reality of the Left’s race delusions. Last century, Progressives came to the conclusion that the obvious racial disparities in the world were solely due to racism, specifically the racism of whites toward the world’s non-whites. Everything that defines the American Left now is based on this assumption. This a lie, not a sin. The sin was that the American Right, or at least those who came to define the Right, never honestly challenged this claim.
Instead, Buckley-style conservatives accepted this two part assumption about the world and tried to fit their ideas within it. This was mostly expedience. By going along with the Left’s egalitarianism, they could have a place at the table. With the Civil Rights Movement, the Left claimed the moral high ground on the matter of race. Confronting them on the reality of race would have required courage the conservatives did not posses, so they chose to make an accommodation with the Left. Cowardice became a feature of the Right.
