I lived through the turmoil of the Vietnam and Watergate days. At no point did I ever encounter people who felt that our civilization was in peril.
Now, however, that is a frequently-mentioned worry. Institutions that once were bulwarks against craziness from either the Right or the Left are now seen as either too weak to mount any resistance or, worse still, as part of the problem.
The concerns don't just come from one ideological zone. Liberals, moderates, and conservatives voice their worries.
Extreme parts of the Left are seen as the primary culprit. They have no regard for freedom of expression. Their loathing of our nation is unparalleled.
Get ready. The pushback is coming.
