World War II never happened and according to some loonies it was a false-flag event... Just kidding.
What has also been described as a false flag event is the Holocaust. "It never happened"... This is part of a sore point that is presently dividing the Greens in Canada and it appears that some people in the alternative media are taking the side of the deniers. I wish it could be otherwise. The Jewish question has hanged about for centuries in Europe. Way before the Holocaust took place in Germany, there had already been some mass-murder of European Jews going back to the crusades. It was Charlemagne who actually stopped some of these persecutions. In Charlemagne's days, the Catholic church forbade Catholics to lend money, thus Charlemagne gave the Jews the rights to become lenders and collectors of cash, while he took his own cut through taxes.
