Only one way...do not let muslims in...ever!
Muslims have been kicked out of Europe several times because the were causing worse problems. Some of the Christian West's worst atrocities have come about dealing with islam.
You would think that people who can read would understand that the teachings of the koran have not been changed so we will always have the same problem.
The problem: we refuse to learn what history has taught us! It is only going to get nastier. We now have two choices....fight and get these people out of our societies or to manageable numbers with in the societies,or slowly surrender. Politicians of Europe will have to go through many many atrocities before their populations will allow them to fight.
