Also ensure that no muslims gets a modern education - strictly maderasa education, no one should take interst receipts from bank depsosits, no one should go near stock market , keep the women veiled in house only. This will finally mean that Muslims remian poor, uneducated and incapable of causing major harm. You dont cause much harm when you fight with swords these days like it used to be till 200 years ago.
We have to fear only a rich , sophisticated muslim. The 9-11 attackers were all rich, modern and sophisticated muslims
