I have the opposite view.
The fatal flaw in the American experiment wasn’t the White race, Anglo-Saxon culture, Christianity or republican institutions. The cancer was liberalism which has metastasized to the point where it has sickened and overwhelmed its host and unleashed a tidal wave of racial and cultural degeneration. Liberalism is what has “continually marred the potential of the overall image.”
“One way of thinking about my talk today is that I’m inviting you to see a fatal flaw in that pattern already on the loom, one that has continually marred the potential of the overall image. To put it concisely, that flaw is the idea that America was divinely ordained to be a promised land for European Christians. And underneath that vision, is its presupposition, that white people were superior to all other races because they were the bearers of “civilization” and Christianity. This is the logic of the Doctrine of Discovery with its Christian justification of white supremacy.
But 200 years ago, we also began a project of weaving together a pluralistic democracy. These fundamental contradictions, one threatening the coherence of the other, remain with us today. …”
Abolishing the gender binary is the latest bitter fruit of cultural liberalism.
Today, if you oppose pumping adolescents full of gender bending puberty blocking hormones, you are a “semi-fascist” enemy of Our Democracy. This is the sort of “progress” it has led us to.
Note: As I have shown, this problem was understood as far back as the 1850s and motivated secession and caused the War Between the States.
