Let me get this right, are you saying Alexander the great can destroy the Persian Empire because the Greeks felt a superiority urge but their actions are insignificance if is in comparison to anything done by Christians? Next you would be telling me Jenghis Khan was a saint simply because his actions were outside of Christianity.
I would address this later as it beggars belief so I would come back to it after I clear up a few things with you.
First let me accommodate your history knowledge and you educate on one instance, yes just one instance of how let me see how did you put it? "Of how Christians killed to show domination out of sheer hatred." I may have missed that in the history of this planet so please educate me. Where did this great hatred and the desire to dominate another race take place in the Christian calendar, what were the names of these group of Christians? Where was this war fought and who were the opposing parties?
To make sure that you understand exactly what I am asking of you, please keep this in mind. When Muslim go to war in the name of Islam it is called a "jihad." When Christians take a similar action it is called a "Crusade." I know of one crusade in world history but since it was not fought out of hatred and a desire to dominate as you put it, I must be missing other crusades, so please this is what I need you to educate me on.
