While I don’t agree with your conclusion/personal opinion of more repressive politics as the solution to this, I still want to thank and upvote you for explaining the situation and the resulting political climate in Sweden in a bit of detail.
IMHO, none of that justifies voting for far-right or even fascist parties (like the AfD over here in Germany), but I can absolutely understand the reasons why people do it.
