"The greatest tragedy in mankind's entire history may be the hijacking of morality by religion."
-Arthur C. Clarke
One of the first debates of conservative Christians against those who believe in no gods, is that one cannot be moral without God. I'm sure Muslims and other faiths use the same argument in countries where Christianity is not the majority-religion. Ultra-evangelical Christians are often delusional enough to believe that only Christians can be good. The two most charitable men in the world are Bill Gates and Warren Buffet. Bill Gates believes more in science than religion, while Warren Buffet certainly is the more irreligious of the two. What motivates them to do good? Common human decency maybe?
