I'm not sure how the argument that Jesus said this and Mohammad said that makes any difference to the fact that both Christians and Muslims have killed and continue to kill in both names, Jesus and Mohammad, as you pointed out earlier. Now the goalposts will be moved to "Well, those are just crazy people, not real Christians.. Real Christians wouldn't do that...". No way, real Christians wouldn't keep slaves.. Real Christians wouldn't subjugate an entire group of people.. Real Christians hate the sin, not the sinner.. And all the other logical fallacies we've heard a million times before.. Like you said, it's all semantics.
And the reality remains, religious people - Christian and Muslim - rationalize their actions by what they believe and innocent people die every day because of it
