Left-wing liberal leaders do not lack the intelligence to recognize the suicidal policies they are pursuing. They are deliberately facilitating the policies of cultural suicide to create the social chaos necessary to eliminate their nation states and globalize the world under one-world government That is the motive for their madness.
Their seemingly bizarre policies create an atmosphere of such anxiety and cognitive dissonance that people are overwhelmed and paralyzed trying to make sense of the nonsensical policies destroying their cultures. Most people simply cannot absorb the shock of leaders who are deliberately trying to destroy the sovereignty, borders, and national cultures of their own countries - it is madness. Most people have enormous difficulty accepting the fact that their left-wing leaders are purposely lying to them, distorting reality, and manipulating the news to disguise their destructive motives. Rather than face this intolerable truth people often withdraw into unreality and pretend it is not happening - they choose subjective reality to find some relief.
