As a Catholic I know someone who is pro-choice, etc. is not really Catholic. I have a harder time saying that a Muslim, who is a radical Muslim, is not part of Islam. It seems to me that Islamic history is chock full of "militant" Muslims who were (and ARE) considered Muslims in good standing or of good memory even though they murdered thousands and thousands of non-Muslims.
No...Islam is NOT a religion -- it is a murderous cult. Anyone for starting the Third Crusade??!?
