This is nature in action... The strong eat the weak and it has jack shit to do with being a refugee (a lot of these young men aren't even from Syria). Europe has worked hard since WWII implementing socialism, breaking down families/people, and political correctness (focusing on the subjective feels instead of the objective reality). It was either going to be Islam or Russia/China and we've known it for decades.

Plenty of people are demanding we be next.
