In The Road to Serfdom, Hayek noticed the many students who went to Europe (especially to France and Germany) to study in the 1920s and 30s:
“Many a university teacher during the 1930’s has seen English and American students return from the Continent uncertain whether they were communists or Nazis and certain only that they hated Western liberal civilization.”
There are false equivalences — but differences between “far-left and “far right” are not relevant to evaluating those who arrive at protests armed with weapons and primed for violence.
The true equivalence is the underlying ideology of anti-individualism, anti-reason, and anti-liberalism. That ideology can come in variations, but our generation’s students still learn it from the same French and German intellectual sources and still militate for the same methods and results.
