Is a Nice Muslim a Good Muslim?

Is Good Muslim a Nice Muslim? wonders Mr. Bill Warner, founder of online portal dubbed Political Islam in a piece he wrote in the aftermath of the Ft. Hood killings. In it, he reminds readers that in Islam, you can either be a Muslim or not, rather than a "good" or "bad" Muslim. By making central the point that any person who does not follow the creed of Islam is considered a "kafir", Warner shows that Muslims are endowed to kill all "kafris", even if they seem like nice people. He then claims that it is by following the example of Muhammad that Muslims are inclined to murder all others, thereby showing that a good Muslim means bad news for Christians and Jews.
