The problem in Sweden is--you have largely separated yourselves from them. Especially the well to do Swedes. If you live, shop and stay in the "right" areas you can go weeks while barely seeing a Muslim. It makes it very easy to conveniently forget what is happening and Swedes, as a whole, like to avoid unpleasant situations and confrontation until it becomes a much worse problem than if you'd have handled it sooner.
Very ease to get lulled in complacency there. Part of what I love about it but very dangerous in this instance.
