Pot, Kettle.... however, nobody forgets the Russian, German, or Chinese genocides. So it is useful to remind people that places like the UK and Belgium for example, are built on a pile of skulls.
It is illegal in Modern China to talk about the crimes of Mao Zedong and the victims of the 'Cultural Revolution'
This was a headline from a Russian English paper today: "Many Russians no Longer Hold Stalin Liable for WWII deaths" - can google.
And: The Brits and Germans DO acknowledge their crimes, and they are overcompensating with counterproductive POLITICAL CORRECTNESS hence the migrant crisis! Same goes for our liberal revisionists here at home. Tearing down statues even of Jefferson and Washington!
