Bah, any comparison of numbers would leave Muslims in a distant second place. American terrorism across the globe has no competition at all. How many dead in Vietnam due to American terrorism? How many dead in Iraq? Millions. Not to mention the millions upon millions that continue to suffer due to American terrorism and evil. The typical American just shrugs and says, "Oh well, we are still the good guys." A complete brainwashing of the public to accept American evil as good while those that suffer under the American boot are actually the bad guys. Right now we have a blatant example of the Americans in bed with the Saudis. Both of whom are involved with and conducting what amounts to terrorism in the Middle East. One day when the Saudis have served their purpose they will become victims of American propaganda and be overthrown through political manipulation of outright bombardment.
The vast majority of death, destruction and suffering across the world in the last 100 years has been caused by non-Muslims. WWI and WWII were mainly large groups of White Christians killing each other. Then we had the Cold War with America and Russia manipulating nations and causing wars across the globe for almost 5 decades. The Muslim world was not competitive at this level of terrorism but the end result for the Muslim world was a pack of slippered fanatics, American trained and supplied, who caused (and continue to cause) havoc in the Muslim world and give Americans an excuse to continue their terroristic ways in Muslim nations.
Regardless, this pack of slippered fanatics living in the mountains of Afghanistan or the sands of Iraq/Syria have little to no power on their own accept that they occasionally convince some loser to act out and actually pull of an attack in the West. They only have power when they are nurtured, trained, supplied and guided by their American masters. That anyone in their right mind is convinced that the average Muslim is comparable to one of those fanatics is the result of American propaganda.
