The issue here isn't just that they won't integrate, foregners are essentially in control of many areas of towns or even entire towns, with people routinely getting robbed and assaulted. Recently the government mandated all municipalities to take in migrants, so this is now a problem everywhere to differing degrees, only with a few exceptions like large municipalities where they can be segregated. Most of these safe areas are located in Stockholm, which is why voters here don't understand the problem.
