revived memories of France's Muslim immigrant disturbances of recent years
Never heard of that. Interpreting infos to make your point is not very objective. This is called misinformation. A very widely used strategy today I must say.
These people came from poor suburbs. There were Muslims, but there were also a lot of Whites. Strangely, nobody noticed them.
I agree tho that the system sucks, the immigrant policies have to be discussed, a lot.
But 'multi-culti', a very trendy word in Poland lately, has not much to do with this.
