What does his peripheral connection with those who died in concentration camps have to do with his Holocaust denial?
Germany is around one third Catholic, then and now, so Catholics died on both sides of the war.
But there was no specific animosity towards Catholics in the same way that the Nazis hated and persecuted the Jews, and put forth propaganda justifying their wholesale slaughter and the plans for their eventual elimination through genocide “the final solution” to the “Jewish problem”.
So if the figure was three million instead of six million, does that make the Nazis only HALF as reprehensible, only HALF as evil, or just less competent in their perfidy?
