As an ex-Muslim this is true. People who are supporting Islam need to read the Quran then judge all the religions. Jesus never use swords or other violent and deceptive action to promote Christianity. Later other followers used that. But all came out of those era long, long time ago. Unfortunately for Islam it sticks in 1400 years ago. If those people had a brain just understand what they are reading then you will see the Islam would have progress like rest of the other religions.
