There is something to be said for being so open-minded that your brains fall out. This appears to be what has happened to Sweden. It happens in all countries where liberalism takes root and flourishes. Gradually but inevitably, the liberals let in the elements that destroy their utopia.
Remember when Sweden was the go-to country for liberals in the news and at home? “The Swedes are so much more civilized than we are, and we should emulate this law” kinda stuff. Sweden had government-provided day-care. Taxes were horrifically high, to the point that marriages where one partner stayed home were nonexistent. For that matter, marriage was pretty much optional (the kids were supported by the government, not the parents). Sex laws were liberalized. There were all kinda Affirmative Action laws (mostly for women, since minorities were not really a big issue back then). And so on.
In light of that, who else is unsurprised by the news that Sweden has been over run by gangs and terrorists? Committing cultural suicide that way is just an invitation to the barbarians.
