It could be that many muslims including the ‘moderates’ do not know all that the Koran is about , very much like people of other faiths who do not know of the teachings and obligations of their faith. However history has given a good indication of muslim intentions for the world.
What the Koran says or does not say is not the main issue. They use it as an excuse to blow up innocents, conquer, and enslave. That is the issue.
