Daniel S. Fletcher said this quote
“ Extremism stifles true progression in all fields of human advancement; it is a detriment to everything but war, tribalism and the personal power of Nietzschean entities, striving only for the narcissistic vindication of their ego and will. The enlightened mind knows that all is challengeable, ergo questions all and thus, learns and grows; progression. The weak and narrow mind makes its beliefs sacrosanct; fearful of challenge, their creed becomes unalterable, defended with violence. Political extremists, much like religious zealots, are the latter. They destroy what they cannot convert. They annihilate those they cannot control, or force to conform. They have found no peace in life, no love, and so promote war and division, as emotional cripples – inflicting their own pain and misery and malignant stupidity on the world. Their language binds people together, but only by stirring the darkest excesses of the soul; language of hate, and intolerance, fear and conspiracy, and the need for vengeance. In war-scarred Europe, these cripples direct mass-psychology, and would make the world in their own likeness; mutilated by violence and tribalism and hate. ”
