I view this bunch as either Muslims who refuse to read the Quran and face the truth of their faith, sort of like "progressive Christians" who advocate homosexuality, anything goes etc.
Possibly the "progressive Muslims" are even a public relations outreach by groups such as CAIR who see the handwriting on the wall and desperately want to paint a picture of peaceful, normal neighbors before the inevitable happens.
Is it OK to be a progressive Christian...but not a progressive Muslim? Why is it that the progressive are still Christians, but the Muslims that do not believe in this terrorism obviously are not Muslims? I believe, just as there are those that interpret and follow the bible differently, there are those that interpret and follow the Koran differently. Why not just concentrate on the ones that are actually doing something illegal, instead of on all Muslims?
