Which is exactly what we should be trying to help Islam achieve...and we don't get there by calling a Billion of them "radical". We get there by trying to isolating the proper nutters (by their scale, not ours) from the rest of the group, and then allowing legitimate Islamic reformers the freedom and safety to win hearts and minds with arguments from within the religion. Another point Sam Harris has made regarding the Christian reformation is the massive amount of water carrying one simple line in the bible has done, the "render unto caesar" line basically does the theological heavy lifting for dividing church and state. It's in our best interests to create as solid an atmosphere as we can for the islamic reformers to find their own "render unto caesar" arguments in theirs texts.
As they liberalize, other bad ideas currently sanctioned by the faith (and there's a lot) will also get cast aside.
