People move yo. It’s what we’ve always done and will always continue to do. Wherever things are shit, people will move to places where they are better.
I can’t find any figures showing an actual crime wave in Sweden (excepting a sharp spike in 2020 followed by a significant decline in 2021, but 2020 had other circumstances that contributes that are distinctly different from immigration). What are you talking about? Right-wing parties always talk about how much worse the crime rates are due to immigrants, but data never seems to appear which supports this.
You can have a look here (government site in Swedish) for crimes divided by category:
https://bra.se/statistik/statistik-om-brottstyper.html
Whilst the sum total of crimes has fallen, the amount of serious violent crime has significantly increased and in some categories to never-before seen levels in Swedish history (bombings for instance).
In these statistics I would highlight murders, organised crime, threats and attempts to influence society, threats and harassment, weapon crimes, sex crimes and vandalism.
The problem with that is that you are using facts and evidence. This already dismantled the entire position and now nothing can save this guy
