If, as is claimed Islam do not support these terrorist types then why are they not expelling them via Takfir? Why are all the imams of the world not making it clear that they are not going to get their 70 virgins in heaven if they don't revert to being, as they claim, the religion of peace? Why are extremist hate preaching imams tolerated? I'll be more inclined to accept that they are not giving tacit approval to these atrocities if they make some attempt at putting their own house in order.
