For a person born in Germany, raised in Germany, taught to speak, read and write German, their homeland is Germany. German Jewish victims of the Holocaust ought to have been extraordinarily repaired, and given the pleasure of seeing their victimizers fallen in disgrace, tried, condemned and punished (part of which did happen), not told to pack their bags and leave to a country they’ve never set a foot in. The idea that someone who’s born in a specific ethnic group has their “homeland” at some special, historical place is an extremely ideological view that has much more to do with nazism than with the ideals of freedom and human rights.
By the way, you haven’t answered my question. In your racist worldview that ethnicities belong to specific strips of land, where do the Romani belong?
