I mean the "rape gang" thing was discovered over 10 years ago. Not saying it isn't a big deal, not saying that authorities could have / should have done things differently... But that was a big "Elon tweet" of last year that turned out to be majorly misleading at best.

There are competing narratives here, and as is the case with many things, the truth is somewhere in-between. This narrative (the OP fake poster) comes from the "Camp of the Saints" idea that Western civilization is being overrun by brown people, and these "barbarian hordes" are being welcomed in by self-hating White people.

The opposing narrative, which is (perhaps) equally wrong, is that there are no real problems with Muslim integration in Europe, and everything is going swimmingly. The truth as always is somewhere in-between; from my (libertarian) perspective, the fundamental issue is a lack of economic opportunity created by stagnant, over-regulated economies in the Eurozone.

Stagnant economies + lots of underemployed men is a recipe for disaster, whether they're white, black, Muslim or christian.
