Islam, since their official inception in 622 A.D., now 1,400 years, has massacred 669,000,000+ (six hundred, sixty nine million plus) non-Muslims, aka, infidels.
They do not melt! No ideology has ever been as genocidal as Islam, - while simultaneously convincing much of the world that they are just like other "religions."
Actually, they claim superiority, and will kill you if you disagree.
You are absolutely Spot On that is their desire to convert the world to Islam or face death or slavery !
Ironic that the progressive leftist liberal Democrat commies praise Islam and hate Christianity two totally different beliefs one preaching death and the other God's love and peace !
