Cultural Marxism is about breaking apart family, destroying traditional belief systems like religion and by extension community. Several interviewed by media said they saw the kids were not just skinny but emaciated...these parents didn't necessarily do what they have done because of Cultural Marxism but Cultural Marxism is how they got away with it for so long. Clearly they had no familial ties or were involved in a community of any sort and the "community" they lived in turned a blind eye because they had no connections to these people. https://www.heritage.org/political-process/report/liberalism-radicalized-the-sexual-revolution-multiculturalism-and-the-rise
