A couple of months ago a typically know nothing leftist sneeringly demanded my personal definition of Cultural Marxism. I was busy and didn't deliver it. But here you are doing it for me; for which I thank you 'V'.
Cultural Marxism is the direct and mostly deliberate attack on every value you just listed. It is always launched against the citizens of any decent country by internal agitators blindly determined to destroy whatever is right and good about their own nation for the promotion of their own vaguely comprehended political ideology of leftism.
A lot of societal decay was already in the works, but the dawn of "doin' it for DA VIEWS!" truly accelerated impressionsble people to believe blatant misbehavior in public was funny.
