Sometimes, discussions around the theme of Islam turn to who has and who hasn't read the Koran. It's as if your opinion doesn't count if you haven't read the Koran. Richard Dawkins for example has been criticized for his opinions on Islam because he hasn't read the Koran.
To me, it's really very simple, just listen to what the most influential group of Muslims are saying. And the most influential group is The Muslim Brotherhood. All terrorist organizations can trace back their origins to the ideology of the Muslim Brotherhood.
