What do you expect would happen if another million of Muslims come to the country :D?
The problem is many people have no real grasp of demographics or how math works in determing the make up of future populations.
It's not just the numbers, it's the demographic of the migrants (fighting age young men) vs the demographic of the destination country.
If current migrant inflow rates continue for the next five years there will be as many non-German muslim fighting age young men in Germany as ethnic German fighting age young men. Given differential reproductive rates (and the violence used to keep muslim women from marrying non-muslim men) it means a future Germany that is majority muslim and minority ethnic German. There's no getting around that except for changing current policies.
Ethnic replacement has taken place long before the new ethnic group is at 51%. But those who don't understand population trends can merrily pretend there are no problems until they find they aren't in control of their own country anymore.
And who knows more about French cities, the French minister of urban affairs? or some random poster on polishforums? Of course it's the poster!

(the minister claims, unlike those with a real personal connection to France, that there are many neighborhoods like Molenbeek in France, his ignorance must be breathtaking!)
