Should we be concerned about driving cars made by persons of English descent due to the expulsion and massacre of our ancestors by the ancestors of the modern Americans? Perhaps refuse to buy anything made by Blacks (descended from the Egyptians) or Hispanics (some of whose ancestors lived in Spain)? Boycott goods made by descendants of the Romans (pretty much all of Europe and the Americas).
And how do we deal with the fact that cars are really produced internationally. We could refuse to use anything produced by goyim.
And should we deal with the fact that for the last 70 years Germany has been friendly to Jews whereas many of the countries that opposed the Nazis are no longer friendly.
Also Germany has a retirement age, so we can be quite assured that no Nazis built a German product you buy today.
