That’s the great fraud of the debate
Either allow mass immigration of non-European peoples who have no cultural, linguistic or ethnic connection to Germany, who mostly wind up on the public dole
Or you are all NAZIS!
A false choice.
Germany could offer Hutterites, Amish and other German speaking people to settle in the east for free land. You get German speaking people with a high birth rate, happy to repopulate the emptying country side.
