> How can you "remigrate" Swedish citizens? They are citizens

This is answered in the first para of the linked Wikipedia article. "remigration" is not the parent poster's term, your misunderstanding of it is not on them at this point.

> Are you talking about immigrants (who are guests in the country)

No. and also, that statement about immigrants is false as a categorisation.

how can you deport Swedish citizens? is there any mechanism in the law allowing to deport their own citizen? If not, then this whole talk is solely about immigration.
