I remember having read a fiction book about that called "Kalifornia"?
1)We would possibly be writing our posts in German and have it censored by a "
prüffungstelle" .
2) some of us would probably be deported, killed etc..
3) The survivors would be educated with Nsdap ideology and wouldn't need to discuss as we would all be brainwashed and have the same opinion.
4)There would of course be no middle East conflict about Israel that would not even exist .
5) "1984" but worse... scary thoughts, aren't they?
