Are you really implying that white supremacy, the very thing that in my parents lifetime was the law of the land, has been reduced to a boogeyman? That is unfortunate. I'd love to engage with you more, and provide some reading or sources that can maybe away your view.
Im not the person you're responding to, but I agree with their post.
In my opinion, mainstream American Conservativism fell from grace long before Trump. Coincidentally for the topic at hand, I believe it was when they made a pact with the evangelical Christian community that they lost their way.
An ideology can not support both small government and personal freedom and fight for banning abortions and gay marriage. They are, on their face, opposite beliefs, but the Republican party needed to bolster their base, and taking on the religious community was a marriage of necessity. Unfortunately any coherent message of actual Conservativism has been lost in that attempt.
Libertarianism was never "actual Conservatism." Real conservatives have been bemoaning the dominance of libertarians within the Republican Party for decades now. Actual conservatism means hierarchy and authority, crushing criminals, and enforcing public morality.
