The truly interesting times™ will be when SHTF in the next 4-8 years, and the SWPLs become personally affected. Already, non-western immigrants, up to the 3rd generation are moving into previously homogeneous areas, and their ways are sufficiently different to cause irritation and low level conflicts. What's more, the establishment is literally spraying the country with reception centers for "refugees". This is also true of currently nicer areas. When their wives, sisters and daughters get raped, their sons beaten and robbed, things will change.
Pain will be their teacher.
