I think reading the full Quran is immaterial to this discussion (I haven't read the Holy Bible fully either...
gasp!). I rely on the testimony of experts on Islam, which you fully disregard even though you are not an expert yourself. I also haven't read every issue of The Watchtower but I still have an opinion about Jehovah's Witnesses. I don't find reading holy books about religions whose beliefs I don't share
all that interesting.
I understand there are Islamic extremist groups; I've never disputed that. I'm arguing here that it's the extremism and not the Islamic that's worrying. I've read about Islamic culture and its history, and much like Christendom, it has both admirable and reprehensible parts. It's simply not true that the majority of the Muslim world do or support violent terrorist acts. Your position simply doesn't stand a reality check.
Have you read the Quran back to back, fully, including the verses that preach tolerance and compassion?
