I would encourage everyone to listen to what Robert Spencer has to say about the threat of Islam against Christendom and the world. Spencer is a Melkite Greek Catholic from Lebanese and Syrian decent. He has studied Islam extensively and is often a FoxNews contributor and has written several books which have been on the New York Times best seller list.
Robert Spencer is Director of his website called Jihad Watch. It's a website where he compiles all Jihad-related articles into one location for the viewer to get informed about this real and serious threat. His website is http://www.jihadwatch.org/.
