You linked to a blog post with a large illustration depicting a "typical leftist Internet troll".
I've spent over 30 years of my life in Nordic countries. These stories of embedded lawless mini-Afghanistans ruled by local Sharia tyrants don't reflect any reality I've ever seen.
No one is claiming that they are "lawless mini-Afghanistans" in Sweden, as you stated.
(from the article I linked to: "To the best of my knowledge, there are no Shariah patrols in Sweden.")
But there is enough evidence to state that there is segregation.
"Segregation (noun): the action or state of setting someone or something apart from other people or things or being set apart."
