You're right that there are thousands of Christian sects in the world today.   It is foolish to put them in a single basket because they have some very different interpretations of the Bible.
 
I'd guess well over half would disagree that You have the only sophisticated interpretation of the Bible.     I'd be glad to have years of conversation on religious theology (on top the decades I've already spent) with you.  This is not where I'd choose to do it though ;-)

Your opinion, or mine doesn't matter much in this context.   The facts are that the Christian church is ripe with atrocities throughout its history committed by people who thought they were the True Believers.   Some of those theologies that led to false persecution of 'heretics' still exit in the Christian church today.

You argument implies all Muslim theologies are bad, all Christian theologies are good.    You can't stereotype either faith and Not show bias/prejudice/and in some cases discrimination.
