When one is not truly right, one becomes self righteous. It is the refuge of the mind that has not learned critical thinking, nor is fully developed..These kids remind me of cult members - and actually they Are in a Cult. Their only source of information is from each other or their "teachers" (Indoctrinating propagandists). To not go along with the other students is the most frightening aspect of all.
Note all of the "selfies" being taken -"Here I am protesting". Their narcissism also contributes to their suggestibility factor. 
There is also an elitism being exposed - "I am a "Educated" person". Their professors encourage this, just as a cult leader encourages his followers to believe They are the "Chosen".
