Better to be ignorant than misinformed. Islam is not a religion it is a government with a religious component. Teaching it is anything other than what it truly is should be a signal to any conservative but apparently it isn't. Wonder why? Could it be GW's assertion that Islam is a religion of peace in spite of the fact history reveal that for the lie that it is.
A Muslim recently asserted to me that the Islamic wars of expansion were strictly “defensive” actions, and that Muhammad never personally killed anyone.
What have you found to be the best factual way to respond, other than simply asserting that is a lie?
