"Europe already seems like it is on the brink, with Patrick Calvar, head of the General Directorate for Internal Security in France, predicting the country is on the verge of a civil war."
Frankly, an all-out civil war is exactly what's needed in France.
A (cough) "cleansing", so to speak.
There's nothing unusual about this, nor should it lend itself to bad connotations.
Europe has had to rid itself of muslims once before in its history. It was not done bloodlessly.
If the Reconquista was not "a cleansing", what was it?
This is not something we should shy away from.
Quite the contrary, we should -welcome- it.
It's called "self-preservation"...
