Tolerant is the wrong word to choose because tolerant doesn't mean "accepting" it means... to tolerate.
And the most extreme position they have stated is that "it doesn't matter if you're born here, if you commit crimes and don't respect the culture you should probably leave".
That is an extreme position, but it's not as black as people seem to paint it, which implies heavily that the party is just simply racist against non-swedes.
The actual racist party is the second most voted for party in Sweden, I think because of how intolerant the society has been about talking about the issues caused by migration. That is my own opinion though, as a migrant, living in the city with the most migrants in Sweden.
> don't respect the culture
That's where it gets messy, at least in the States.
note: I have family in Sweden that are non-white but I've never discussed the issue as it felt a bit too "delicate"
