From his web site, he is clearly Sunni, but above all a Sufi. Kabbani is clearly the most prominent patriotic Muslim cleric in America. His organization may not be extremely large but is large enough for the blanket condemnations of Islam sometimes seen on FR to make me uncomfortable.
Maybe non-violent Muslims need to change their name. After all, we had to change ours.
Long ago, people who believed in liberty called themselves "liberals". (These words even have the same root!) After the term was hijacked by people who believed the opposite, we had to change our name - to "conservative".
The word "Muslim" has roughly 100% negative connotations. Anyone who stands up and announces he is a "Muslim" must live with the consequence that most listeners will assume he wants to kill us - just as anyone nowadays who stands up and calls himselve a "liberal" must live with the consequence to most listeners will assume he believes that Big Government has the solutions.
Perhaps those Muslims who oppose everything commonly associated with Islam should pick a new name. How about "Sufi"?
