You are right though this is where we differ. I would advocate finding a way to lessen the anti western feelings that the bloke was talking about as i think this would lessen the number of people being influenced, lessen the number of people making speeches and lessen the number of extremists (rather than just stranding them somewhere else).
.
These people were influencing long before the ISIS came along, long before talk of banning the burka, i suggest it is naive to think it would stop/lessen now.
Even you must realise living in Oz that the sweeping under the carpet/ignoring has had profound affects in towns like Rotherham. The problem will not go away by ignoring or the continual appeasement, that ship has sailed. Again we differ.
