I never denied Christianity was in some ways spread by conquest, many other religions have been as well. What is being denied here is the historical fact that the Muslim religion is without equal. None has spread so far, so fast using the sword as its' primary spreader of the word.
It's not accurate I've ignored Christian conquests even mentioning their violent acts in driving the Muslims out of what is today central and southern France with wholesale slaughter and violence, many of the Crusades involved towns being sacked and murder by the thousands.
But history doesn't change just because some don't like it...or are just now learning it existed. Anyone can go do the homework and easily see I'm quite correct here. I can offer some great reads David.
And yet most of the new Muslims during the 1st century of Islam weren't conquered people... You're clearly confusing the Caliphate with Islam and it's making you look uneducated on the topic.
