They have been told that everything in the world is somehow related to race, class, gender, sexual orientation, or supposed physical ability. They understand that evidence and truth are things used by racists and other losers. They understand that rights are important, but personal responsibility for actions are not. They have been told that truth is relative and thus myth. All ethics are situational, not absolute.
Any religious belief is suspect or bogus.
All these things are accepted without argument or reasoned skepticism. Failure to conform, to be with the cool set, is to have a stinging epithet hurled at you or a wall of silence instantly constructed to isolate you. Once labeled and isolated, no one has any obligation to listen to anything you might say. The price for breaking the rules of never questioning, never doubting, never asking for evidence, and never noting contradictions and inconsistencies is sure and uncompromising.
