Fear of violence from "the others" is also a strategy historically used by fascist governments.
I think the fear is somewhat justified when men, women, children and even babies in prams get mowed down on a promenade when they are enjoying a festival.
You do remember the Bastille Day attacks in Nice, right?
That attack on a music concert in Paris?
The slaughterings that happened over a freaking cartoon in a satirical magazine?
That's just the last year or so in France.
Sweden's crime rates have soared through the roof almost exclusively thanks to these cockroaches.
That's public domain, not propaganda.
