remigration

To remigrate used to mean to return to the country from which you and originally migrated.  It could be then generalised to movements between organisations or even states of mind.  You could start out in one political party, be attracted to another and then realise that you belonged in the party that was your first choice and natural home.

In the current context of migration into European countries, the Identitarian Movement was born in France in the 2000s.  It defends the rights of White Europeans to keep their culture and racial identities.  The solution to the increasing adulteration of the culture of  European communities is to remove the immigrants that have flooded Europe and turn back the pro-diversity policies of European governments.  This removal of the immigrants has been called remigration, though some have said that it is the euphemistic name for ethnic cleansing.

And now we have the nationwide March for Australia.  The organisers claim that they are not right-wing and racist but they merely wish to protect the traditional Australian culture and way of life.  But remigration is part of the process.
