"Der Grund, warum wir von kulturfremden Völkern wie Arabern, Sinti und Roma etc. überschwemmt werden, ist die systematische Zerstörung der bürgerlichen Gesellschaft als mögliches Gegengewicht von Verfassungsfeinden, von denen wir regiert werden. Diese Schweine sind nichts anderes als Marionetten der Siegermächte des 2.
