Churches seem to have withdrawn from educating followers in the very capacities which constitute their humanity - which, of course are the very ones that enable real faith and faithfullness: discernment, logic, empathy and compassion. 
Because religion has failed to evolve its theology along with social and scientific reality they have chosen adamant resistance, with beliefs that are not founded in, and/or are contradicted by "the known".  Rather than humble honesty of Christ they choose simplistic pandering dictate of unreason, reinforced with emotion -  rapture(self)/vitriol (other). Rather than "explanation" they opt for selective literalism; rather than freeing from fear and hate they opt for intimidation and exclusion; rather than the evangelization of love they focus on hate for the doubter and dissenter; domination rather than leading.
Radical fundamentalism is the rejection of humanity and of God. It leads to radical fundamentalist terrorism in religion, politics, society.
