Here is another example of immigration resulting in cultural enrichment:

“Stockholm police expert Gunnar Appelgren has described Sweden as being like a “state at war” following a record number of 44 fatal shootings across the country this year. Appelgren, who serves as the coordinator of the Stockholm police force’s gang conflict programme, said that the situation regarding gun violence was, “reminiscent of some form of state at war,” Swedish broadcaster SVT reports. Police in Sweden have made 299 arrests from the start of this year until November, compared to a mere 58 arrests during the same period the year before. They have also seized around 825 firearms in 2018, up 30 percent from 2017 and the number of hand grenades seized has also risen. The total number of shootings has reduced from 324 in 2017 to 272 in 2018, though the number of fatal shootings has increased. Stockholm’s police have managed to make inroads into the problem of gun violence, the vast majority of which is related to gang crime, reducing the number of fatal shootings from nineteen in 2017 to eleven so far this year. Police say their efforts in calming tensions among gangs in the heavily migrant-populated no-go suburb of Rinkeby are partially responsible for the lowering levels of violence.”
There is simply no reason for supposing that this will get better in the future and every reason to see a cascading flow of violence sweeping conventional Swedish society away. Perhaps it is for the best, in the long-run.
