Not weird at all when you understand the goal of the one world government. Progressivism requires the rewriting or deletion of previous historical events in order to enate their own agenda. What children today don't know, or when they don't know the truth i.e. Iran's declaration that the Holocaust never occurred, allows them to believe many evil things.
I personally think it's part of prophecy. Whatever it is, it aint' right! But there's no stopping it.
Even our own USA history has been rewritten in many areas ... and no just recently, though moreso recently.
