How can we criticize something if we know nothing about it?

Marxism is not what the wokies and western liberals/democrats and right wingers claim. There is nothing Marxist about what they stand for.

Marx has been a taboo subject in the western world for 70 years.

Learning what Marx actually wrote better equips one to call out the fakery out there.

That doesn't meant you have to subscribe to it. But atleast be educated about it...
