A) Abolish the law, that says holocaust denial is illegal B) Prepare a exhibition or something like that, where lots of evidence is for the holocaust is shown C) Invite people like Achmadinejad and the like to Germany to see the exhibition D) Refrain agreeing into abuse of the holocaust, such as - stop to support Israel unconditionless - Ok, the support is anyhow not so that huge, but still a bit more than sensible - stop to give the Central Council of Jews in Germany the quasi-state religion leader character it has to date. This is rather crass, when compared with similar Christian authorities - stop acting as if the holocaust was the only event in history ever, adjust the school learning plans appropriately as well as in general public live. Almost everybody is exremely annoyed by this. It seems the little rest becomes journalists. Der Amerikaner ist die Orchidee unter den MenschenVolker Pispers
