The percentages are based off of many factors. 2 billion Muslims in the world. Alqiada and ISIS style Muslims make up less than 1% of that population. That's a real study. In 2004 a study showed that less than 5% of Christians have read the bible they preach from front to back. And more than 60% of those surveyed sayed they wanted the Muslims punished for 9/11... which is a violation of jesus' commands. I'm not religious, and not a muslim. I'm open minded and very well studied... unlike most of you Christian hipocrits
