No, not like that at the fucking all. I live in Stockholm, I just came today to my home from a friend's place that is in one of these pesky little maps marking it as a "no-go zone". Seriously, there's nothing alarming there at all, it's a very normal area a little bit outside the center with more affordable housing (compared to the center of Stockholm but not even near "cheap") and that's about it.

I've stayed on that friend's house for the whole of January, daily living there and haven't heard about a single crime happening. Asked my friend's flatmates just now and they laughed about it.

Same thing for a friend that lives inside what some maps label as "no-go zone" in Kista, nothing happened there at all for the past year.

So seriously, the alarmism here is very extrapolated compared to the actual risk. Compare to Belgium as you want but be a bit more honest about your utter ignorance instead of just a "And I don't know about Sweden"-trumpesque discourse.
