Please don't tar all Muslims with the same brush. Most Muslims in Germany are Turks. Their integration is difficult but not impossible.
The Arabs in France, on the other hand...
Wrong! Absolutely impossible as the facts have shown.
1) Turk Muslims have not integrated in over 40+ years in Germany. They integrate as long as spouses they marry convert to islam.
2) Turk Muslims have shown the way to all muslims in the ways of dispensing of millions of Christians. They have had hundreds of years of practice doing it all over Eastern Europe, the Mediterranean and the middle East.
3) Given their history of siding with the wrong sides (Fascists) in all conflicts (WWI and II) there is no doubt that they will side with their muslim goons just as they voted in an islamic govt recently.
