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.
"You" ? Again, I ask you to do the reading and/or query the people advocating for such policies, and not me or the parent poster. Why do you persist in misunderstanding? We might be constrained by the bounds of law and making sense, but I do not think that the people advocating for such racist policies are.
> this whole talk is solely about immigration.
It is not, do not derail.
> is there any mechanism in the law ... If not
Are you ... are you seriously unaware that the party in power can literally make new laws? Or otherwise work around existing laws? Really?
The party advocates for deporting people who are born in the country.
if they really want to deport regular integrated members of society who only differ for their color then I probably wouldn't agree with that policy of theirs if I was Swedish.
The linked article above is literally Wikipedia. You are wasting everyone's time.
Deporting parents (thus with their children) is normal if they are staying in the country illegally without any sort of valid visa or permit, what's the alternative? Give citizenship to anyone crossing the border?
We are not talking about families or parents who visit a country for a few months and give birth, and you know that. We are talking about taking 15 year olds who have only known life in that country and deporting them to a country they've never been to.
> Why would being born in the country give you citizenship or the right to stay?
Because Sweden seems to think so? Many countries offer citizenship if you are born on soil, and while Sweden isn't one of them, it offers expedited paths to citizenship if you have lived in the country for a while. Because most people intuitively understand that there's no sense deporting someone who is more connected to Sweden than they are their home country.
Only ~16% of countries are having right of soil, it's not really the norm and it's mostly actually with many conditions for most, a ton of people are against what's happening with immigration so it's not really Sweden thinks so type of deal here, it's mixed opinion, similar to the US.
