Gregory David Roberts said this quote
“ Fanaticism is the opposite of love. A wise man once told me - he's a Muslim, by the way - that he has more in common with a rational, reasonable-minded Jew than he does with a fanatic from his own religion. He has more in common with a rational, reasonable-minded Christian or Buddhist or Hindu than he does with a fanatic of his own religion. In fact, he has more in common with a rational, reasonable-minded atheist than he does with a fanatic of his own religion. ”
