I don't think there's anyone left around here who honestly believes that Islam is completely harmless.
Most Muslims do practice peacefully just as Witnesses practice their religion peacefully. None of that detracts from the fact that both faiths carry core messages that we all want to see eradicated. Accepting that the majority of Muslims are not rabid terrorists in waiting is not the same as whitewashing the religion or the necessity of Muslims acknowledging the part their core faith has in this. It's not a single source problem and there is not a single source solution.
We don't expect terrorist bombs to prevent our way of life continuing, why should violence on the reverse side make any difference to their ideology?
These type of "kill 'em all" rants just sound like the old Kenny Everret commie bashing general spoof to me...
