This is a good definition:An offshoot of Marxism that gave birth to political correctness, multiculturalism and "anti-racism." Unlike traditional Marxism that focuses on economics, Cultural Marxism focuses on culture and maintains that all human behavior is a result of culture (not heredity / race) and thus malleable.In short, cultural Marxism is a revolutionary leftist idea that traditional culture is the source of oppression in the modern world.
Basically, the society in many W. European countries especially UK, Germany, etc. and also places like San Francisco where any fact that does not toe the PC leftist line is automatically derided as racist, islamaphobic, homophobic, etc. Any movement or school of thought that seeks to undermine and destroy the traditional family unit, cultural identities and traditions, Christianity, etc. - i.e. feminism, homosexuality, multiculturalism, etc.
Even though the USA was the country which carved up Europe between themselves and the USSR, thus condemning Poland to 44 years of Communist rule?
Yup. Along with UK at Yalta/Postdam - who unlike the USA totally disregarded a mutual defense treaty. USA, UK, France were all allies of the USSR - not just the USA.
It's a matter of practicality. Poles simply trust the USA much more for protection and it's been like that whether its PO or PiS in charge. Every government has put the USA as a military ally ahead of any EU nation. For one, the USA is far more powerful than the EU in sheer military strength.
