Not true.
Islam's inhumanity and battle with civilization has been ongoing for five centuries. Their cult excludes tolerance. Their leadership has fostered such horrors as beheadings and death by stoning from the beginning to the present day.
Subjugation of all non-Muslims is their mantra. Don't kid yourself. We are at war and they are winning.
I agree, except for the time frame. 5 centuries is does not go back nearly enough. Mohamad also was a war lord, from the begining.
