In all times, and all countries especially in those countries which are divided within by religious faith, there are always fanatics who will be well contented to be regarded as martyrs.
~ Alexandre Dumas
The dangerous enemies of your species are fundamentalism, intolerance, separatism, extremism, hostility and prejudicial fear, be it religious, atheistic or political.
~ Abhijit Naskar
Religious extremism is fatal to those who don't conform to its values, or remold or submit themselves to its 'principles'. It craves control and power - and power is the one tool that enables it to wreak its characteristic havoc, destruction and cruelty upon those it chooses to label as scapegoats. Giving in to extremists enables them and empowers them - and worse, it encourages them.
~ Christina Engela
We must not overlook the role that extremists play. They are the gadflies that keep society from being too complacent or self-satisfied; they are, if sound, the spearhead of progress. If they are fundamentally wrong, free discussion will in time put an end to them.
~ Abraham Flexner
What is objectionable, what is dangerous about extremists is not that they are extreme, but that they are intolerant. The evil is not what they say about their cause, but what they say about their opponents.
~ Robert F. Kennedy
Extreme right-wingers are known for giving God a bad name; extreme left-wingers are known for giving God a weak name. He's not as simple as conservative versus liberal, old versus new. His wings are balanced. God is both and neither.
~ Criss Jami
Extremists think 'communication' means agreeing with them.
~ Leo Rosten
