It's true that I don't support my overall criticism of conservatism in this article. I do so, however, in a long series I wrote, the links to which you can find in the summary article below.
I agree there are modern forms of tyranny. In fact, I criticize secular humanism, the Enlightenment metanarrative, and the liberal conception of progress on that ground. I view tyranny as a natural intrusion of the law of oligarchy and of certain human toxicities and corruptions into what's supposed to be an artificial refuge from nature. Kingdoms channel these natural inhumanities in one form, and modern societies do so in another (totalitarian dictatorships).
Democratic republics, however, are also modern, and that's where the liberal revolution lies (despite their tendency to concede to nature the gross economic inequality, which is liable to turn them into plutocracies). I critique that revolution but I don't reject it outright.
