Well it has to do with modern marxism. Or how it's popularly known; Cultural Marxism. Everything you describe fits right in to the cultural marxist ideology.I'm not sure how much of it has to do with Marxism. Think about it, the former communist countries (Poland, Russia, Serbia etc) and the present ones (China, Cuba, Cambodia etc) are the least affected by this cancer. Hell, even East Germany is less affected than the rest of Germany.
It is just plain cultural subversion, ****** by a minority whose goal is to create a climate of fear so as to control the people more easily. If you disagree with mass immigration then you're a racist Nazi. If you disagree with gay marriage then you are a homophobic bigot. If you disagree with Islam then you are an islamaphobe. Repeat ad nauseam
In many ways it bears a strong resemblance to Orwellian thoughtcrime. Most people are opposed to what is going on but are too afraid of the vocal minority to speak what is on their mind.
Indeed for good reasons, nowadays free speech seems to mean little. In many countries expressing views that are deemed politically correct can now get you prosecuted under so called 'Hate Speech' laws. Like the Dutch politician Gert Wilders who was up in court for criticizing Islam. To think that some pathetic people would defend this disgusts me.
Liberating tolerance, then, would mean intolerance against movements from the Right and toleration of movements from the Left.[18]
Surely, no government can be expected to foster its own subversion, but in a democracy such a right is vested in the people (i.e. in the majority of the people). This means that the ways should not be blocked on which a subversive majority could develop, and if they are blocked by organized repression and indoctrination, their reopening may require apparently undemocratic means. They would include the withdrawal of toleration of speech and assembly from groups and movements which promote aggressive policies, armament, chauvinism, discrimination on the grounds of race and religion, or which oppose the extension of public services, social security, medical care, etc.[18] https://en.wikipedia.org/wiki/Herbert_Marcuse
Former soviet countries don't have white guilt. They don't have big enough groups of minorities and their societies are still catholic or orthodox. But most importantly the western oriented generations in the former soviet countries appreciate western values more than the west does at this moment.
In the humanities and most soft sciences over 90% of the teachers are leftist and most are outright marxists.
The media and even the president parrot their pseudo science as facts and blasts anyone who does the wrongthink (indeed very orwellian, perfectly dictated by critical theory)
