There is no acceptable level of terrorism. Stop the so-called refugees at the door and tell them to go fix the problems in their own land before bringing their problems to our door. Why are these folk not fighting for their own land? All they want is a free ride in a rich nation. They shirk their duty and then want the West to fix all their problems for them. Europe does not need a bunch of fanatic know-nothings who do not even speak the language of their host country. They care nothing about the culture of Germany. They will ruin Europe and turn it into the same hell-hole they came from. They want sharia law, the rape of women, beheadings and public floggings. That is all they know for a hundred generations.
If the refugees belong anywhere besides their own land, then it would be in neighboring countries, not in Western Europe. The people of Europe are awakening to this truth, and it will not be long before the foolish politicians are cast out in elections.
