>I’m saying there’s a difference between choosing future immigrants and changing the status of people already legally present
I'm sympathetic to this view. But ultimately legal residence doesn't rise to the level of citizenship and will always be 'second class' and subject to changing political winds. A nation should act with the interest of citizens. If allowing non-citizen residents is no longer in service to the interest of citizens, then that's too bad.
But aside from that, the view that once you are physically present in a country you can't be made to leave is dangerous in its own right. This strongly incentivizes closing any and all avenues to asylum or temporary residence due to hardship. If morality dictates there is no such thing as temporary residence, then there just will be no refuge given to the next wave of war refugees. Incentives matter, and your view creates some very unfortunate incentives.
>The concern should rest on someone’s actual beliefs or conduct rather than with the entire group to which they are born or reside. I’d rather see that addressed directly rather than be inferred from nationality or broad group averages
This is where ideals clash with reality. If it's not possible to determine views/culture until the person has demonstrated incompatibility (e.g. committing some crime), this burden is now on the existing citizens to absorb some increased level of crime for the sake of the immigrants. I don't recognize this as a legitimate moral duty.
I'm not saying that non-citizens have identical political rights to citizens or that temporary residence can never end.
What I'm saying is that persons legally present in a country should not be penalized as a group based on nationality, religion or any other broad cultural polling/averages rather than individual conduct and due process of the law.
Citizenship can allow for some distinctions but it does not make non-citizens mere guests whose rights can be revoked at will. A state can regulate immigration but it still has the moral/ethical and legal duties to avoid arbitrary and discriminatory treatment of all persons under its jurisdiction, especially toward people it has already admitted lawfully.
There should never be 'second class' persons under the law and rights should not be "subject to changing political winds" as you seem to be suggesting, because that would mean there are no such thing as universal human rights which would put all persons (citizen or otherwise) in danger of losing their rights at the whims of the state or the majority.
