Oops, probably to late at night when I wrote that. There is no comparison in history that Christian have attacked and killed more Muslims then the other way around and there are way less Muslims to begin with.
Okay, first of all, it's "fewer", not "less". Second of all, history is not defined as "things I'm just SURE are true, no I have no proof, I just KNOW".
I can only assume that when you say "way less [sic] Muslims", you're simply lumping all white people, or all non-Muslims, into the "Christian" category.
Here's some ACTUAL history, as opposed to the "I just know" variety.
Islam has been slaughtering and converting-by-the-sword since its inception in the 7th century. Back then, North Africa was almost entirely Christian, and accounted for approximately half of the world's Christian population. You see an indigenous Christian population in North Africa today? Me either.
And let's not forget the millions of European Christians enslaved by the Muslims, or killed by repeated Muslim invasions into Europe and the Byzantine Empire, which was the cause of the Crusades (yes, I know, you "knew" that the Crusades were an agressive act by Christians on "peaceful" Muslims, but they were actually defensive and a reaction to Muslim depredations).
If you'd like to get more current, we can take a look at the millions of people Muslims killed in Eastern Europe in the 20th century. And that's just their aggressions toward Christians. I haven't even mentioned how many millions of non-Christian, non-Muslim people they've killed in their various attempts to take over other parts of the world.
