I think it's time for western governments to accept that mass immigration is a failed model. Everyone knows it and the far right is getting closer to power every day, when it has not achieved it already like in Italy, the Netherlands, Sweden, etc.
Just yesterday in Germany crime stats were published and criminality has increased by 5% year on year, with a staggering 50% holders of foreign passports amongst convicted crimes. It's insane you can't make that up. Be ready for the progressist rebuttal : "it's because foreigners are poorer on average so they are overrepresented in crime stats". Well yeah this is what happens when you flood your inner cities with uneducated, poor, unqualified immigrants. You import poverty.
