"Loosehead - in the same way that white people give tacit agreement to paedophilia?" - Not remotely similar, look what happens when anyone knows even the existance of a Paedophile in the area, they are drummed out of town, hardly "tacit" approval
"The Muslim council have several times condemned extremists and have Muslim MPs etc." - Great it's a start now how about some positive direct action. Say denounce Sharia law, expel the mad mullah's from the mosques etc
What would you have them do? - As above, start distancing the main religion from the nutters in whatever ways they can come up with, at least show they are not merely paying lip service to condemming the extremists
The majority of Muslims are law abiding people who do not want to be tarred in the same way. then why are they allowing themselves to be tarred by inaction?
