The decadence of the Romans is not much different from the decadence of contemporary "Liberalism", i.e. the Left.
So consuming is the hatred of the Left for America, Christianity, and Western Civilization that they seek to destroy them and replace them with anything--even naziism or its 21st century recrudescence fanatical Islam.
If not checked, the Left will lead the world into a hell of decadence and depravity.
Agreed, though what they'll wind up with is an entire world with all the social amenities of Saudi Arabia.
