Christian Columbus was far worse than ISIS

Despite what Western folklore might tell you, Christopher Columbus was bloodthirsty maniac who committed crimes similar if not worse than.  He killed, maimed and enslaved thousands of innocent Native Americans when he claimed to have “Discovered” the new world.  (Even though it was already inhabited by indigenous people.)  But what a lot of people might not know is that contrary to his murderous lifestyle, Columbus was apparently a devout Christian.

So with that said, should we now all make generalizations of the Christian faith and consider all Christians worldwide guilty for the crimes of Columbus like so many do with Muslims in relation to ISIS?
