is Islam one of the world's fastest growing religions, thru conversion or Reprodution?

there is a tremendous need to address this subject, which, because of crazed Islamic fanatics, strikes fear in the hearts of many non-Muslims. Competing with Christianity,We are emboldened to tackle this subject not only because of Islam's expansion and the coming together of its leaders from around the world, but also because certain Muslim leaders, anxious to rectify Islam's bad rap, are making statements such as, "There are 1.8 billion Muslims in the world,and 99.9% are peace-loving" Islam represents one of the bloodiest, most repressive and unappealing ideologies that humankind has yet come up with.
