And that's the thing so many people just do not understand. True, there are plenty of peaceful Muslims that maybe take the more positive things from that religion as opposed to the violent and negative ones, but the fact remains that according to the Quran itself, all these extremists are entirely supported by what their bible says. All one has to do is start reading the Quran to realize that the book itself has many passages supporting and instructing the slaughter of everyone that doesn't "believe" (look up the verse of the swords to see what I mean). This movie was very insightful into all that madness:
Obsession - Radical Islam's War Against The West
Obsession: Radical Islam's War Against the West
The Third Jihad - The FREE 30-Minute Version
Yes!! The moderates are simply not proper muslims as you have mentioned (the fundamentalist would certainly agree with me) . Excellent point that few understand..
To those really interested in this subject pick up a book entitled Islamn Unveiled by Robert Spencer. A great breakdown of what islamn is really about (hint: it's not about peace)
