The problem is that a lot of Muslims can't properly assimilate in their own countries too and it's really hard to sort through them. But even if you could sort everyone into "Productive member of society" and "Troublemaker forever" leaving the latter to fester in the desert for another 500 years won't help anything either.Tbh it's not hard to see why there's been such a rise in anti-Islam sentiment in Europe. Might be for the best if these Muslims stick to their own counties if they're not willing to assimilate.
These sick fucks are really testing my principles of giving everyone a chance right now :\
