The ones that have been in the country for 15 years should have a permanent residency already (if they don't, then it's very likely they came illegally), which is a valid long-term VISA, in which case I agree that they should not be deported, but the ones that don't have any valid visa, they should be, in what world do we allow people to stay illegally and then what, must steal IDs and forge docs to live correctly and get a job... I feel it also teaches wrong values to our children (it's fine to just stop renewing visa and overstay or just plainly cross another country's border without permission), it doesn't feel right

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.
