I find myself thinking exactly the way TR does concerning this subject. And then there are days when I believe the way GH does. It is a very confusing, sad topic that I seem to wrestle with daily (I read too much.)
All I know is that change is not going to come from within Islam until more of the extremeists are laid to rest and there is a more equitable "balance of power" between extremists and moderates. I am beginning to read of more moderates stepping forward, but I am still of the belief this GWOT is far from over, if only just beginning.
