I agree that Christianity in practice has changed in many ways. So has Islam in practice in many places. However,on the violence scale, Islam is way behind Christianity if you include all the wars. WWII alone puts the Christians ahead in violence.
In what sense was ww2 a "christian" war? We are not talking about violence simply involving people that belong in the islamic world, or profess a belief in Mohammad as the last profit. But violence waged and justified in a name of a religion and based on specific interpretation of a religous text. In fact, such a distinction is so obvious I am left wondering why I need to explain it to you
(only communist dictators Stalin and Mao top the Christians in the last century.) There's also all the USA's bombing wars and occupation, the "secret" wars by stealth and proxy ,and Europe's attempts to hold onto their empires.
See above
Of course, you will say that these wars were not driven directly by religion, and you'll be partially right, but the overall North American-European/Capitalist/Christian worldview has proven to be one of the world's most deadly. We're the people that invented the guillotine, the machine gun, the gas chamber and the nuclear bomb.
1) odd that you would recognize the inherent issues of the comparison and make it anyway
2) if you are saying the west and the developed world has issues and nasty legacies, then I don't think anyone claimed otherwise. But I am unsure how that would address the attitudes and issues under discussion, besides as a means to confuse and deflect from them
3) Dynamics surrounding foreign policy, relations between states, and struggles over various resources are fundamentally different than wide acceptance of the religious belief that apostates should be put to death. And I doubt you would find many in modern liberalized democracies supporting the execution of people simply for being muslim or communists. Which is, if you want to cite the affects of an ideology in relation to another idealogy, in the comparison you want to make.
The comparison you make above takes one ideology, in it's present form, and then tries to compare it historically to a rather large geographic region (the west). Ignoring that geographic region encompassed a very broad collection of ideologies, some that were totally incompatible or even outright abandoned
to say they are not the same thing and unfit for such a comparison, would, again, be pointing out the obvious
4) I'm not sure a comparison of the underlying ideologies that comprise western liberalism and islam really pans out in Islams favor, but mileage likely varies
"But these enemies of mine, who did not want me to reign over them, bring them here and slay them in my presence."
Jesus
Again, no one denied the historical violence of Christianity (in fact, I have cited it numerous times). What was denied was the comparison concerning modern Christianity and islam
