If we don't like PC Liberalism, what is the alternative?
Conservatism or Nationalism? But neither are developed ideologies, because there is no definitive manual for either.
This means neither Conservatism nor Nationalism is strong enough to defeat PC Liberalism.
Communism has been tried and failed.
Christianity is kaput and Judaism is too hard.
One you have eliminated the impossible, what's left, however improbable, must be the answer.
