Academia is solidly left wing. This promotes smugness because they are 'educated' while right-leaning people are workers ('uneducated') or businessmen ('selfish'). This culture reinforces itself by persecuting any dissent. Outrageous claims are praised, not questioned, as long as they support the narrative. After years of exposure most will start to think this nonsense has at least some merit. So schools have become advocacy centers for failed philosophies such as socialism, big government, victim feminism, anti-white 'history', family-hating, and climate change extremism. Yes, real communism has never been tried.
