"Moderate" Muslims should more accurately be called "moderately" Muslim -- they either ignore or are ignorant of at least parts of their faith.
"Moderate" Muslims will quote Muhammed from the early days of his preaching career, when he advocated peace, love and understanding with non-Muslims; not surprisingly, Muslims were small, weak and few in number at the time. He grew more belligerant as Muslims grew in numbers and power. You just can't get around that.
To be fair, Christian rulers at the time committed all kinds of acts that are not acceptable today, but that's the point -- to a Christian, what was acceptable in the 7th century may not be today (slavery being a example). Traditional Muslims are still mentally stuck in the early middle ages.
Sounds suspiciously similar to talk about the mental inferiority of the 'Noble Savages'...
But the New Testament does not have preachings that advocate this. The Koran has some pacific verses but has many murderous verses that advocate bloody war and terrorism. Even being so specific as to advocate beheadings to more easily frighten (terrorize) the opposition into surrender.
Then you have the problem that all Muslims are exhorted to copy and model their life after the most perfect life ever lived. That of Muhammad. (Islam's words)
I will steal it if you do not mind.
