Totally already legal to cross corpses to remove the "fake Swedes." Sweden is for Swedes after all.

Örebro Party leader Markus Allard goes to the election on expulsions. He opens to withdraw citizenship and also expel second generation of immigrants – even if they were born in Sweden.
"I'm prepared to cross corpses," he said.

One suggestion that he has is that citizenship and permanent residence permits can be torn up – with reference to "Sweden is the country of Swedes".

In a section of Yoshi's Podcast, Allard develops his view on expulsions and explains that he prepared to "go over corpses" to bring home unwanted immigrants. The host notes that there will be no beautiful sight when, for example, immigrant mothers who have been on maternity leave for 15 years are to be deported together with their children. "It's not going to be pretty to send these people home," he said. Markus Allard agrees, but says: I think you can handle that optics. Even the children will need to be deported, he explains.

He further explains that many of the problems relate to second-generation immigrants. They are going out too. Even if they were born in Sweden, because they have no natural connection to Sweden. They are not Swedes. They have not become Swedes. It says Sweden in the passport, but they have not been interested in becoming part of Sweden. There's a difference. It's a qualitative difference," Allard said.
