Expulsion can be appropriate for dealing with people who harm society.

It should be used with caution but does have its place.

De-integrating (so to speak) may sometimes be a required first step before effective "re-integrating" can occur.

I don't see a way for expulsion to happen. Segregation in some sense, maybe. But that usually runs into the anti-insurrection problem where suppression becomes repression and breeds contempt, strengthening the factions being suppressed.
