ynvaser: Here are some questions for you.
What do you propose we do with Muslims that are born in your country?
What do you do with Muslims whose country of origin won't take them back?
How are you going to get rid of Muslims, who is going to pay for it? If the Muslims themselves must pay for it, what do you do with the poor ones?
How would you organize that deportation on such a scale?
What would you do with Muslims who do not have an Eastern background but actually are your ethnicity? Surely you know that not all Muslims are “arabs”? Even some of the fanatic ones.
What are you going to do with Muslims who do not openly state they are Muslims? How will you find them? Has it crossed your mind that as soon as you start deporting Muslims many will try to hide their faith?
What are you going to do with Muslims who just leave their Mosques and claim they are no longer Muslims, even if many of them still secretly are? Many of which may even be those extremists you want to get rid of. Has it occurred to you that an extremist in particular would use tactics to stay in a country to damage it in the future?
What are you going to do with the increased rates of extremists? When one side starts hating another and starts acting on that hatred, the other side will react with hatred as well. What I am saying is that as soon as you start deporting Muslims to get rid of extremists you will have even more extremists on your hands unless you can figure out a method to stop that from happening. What are your ideas?

pro tip: Look up how the Holocaust or the hunt of communists in America were organized, you may find many answers to those problems there.
