I think most liberals have the intuition that laws should apply equally to citizens and non-citizens, and I think that's where a lot of the discomfort comes from when we talk about immigration. A citizen who doesn't meet those demands imposed on non-citizens (e.g., language, cultural assimilation, etc.) will never be at risk of deportation, simply because they were lucky enough to be born in the country.

However, it does seem that this Swedish party is willing to "repatriate" even Swedish-born citizens, so at least they're consistent.
