Progressives need politics to be fascinating, spectacular, and sublime. Such needs make progressive politics wildly unstable.
Conservatives are content to have stable and boring politics, though, because religion and art serve their desire for the sublime.
Besides, religion is far better than politics at fulfilling the human need for the sublime. “Spectacular politics” ultimately involves nothing more than worshipping perversity and forcing people to do what you want, neither of which is satisfying for all that long.
