All of those aside from comfort women and Ww 1 historic bits are as real as how Germans raped babies in Belgium in Ww 1, how Iraqi Soldiers threw babies off of incubators in Kuwait in 1991, and how Saddam had WMDs. All of those have been claimed by the Anglo-American establishment, in case you haven't heard.
And here we are today, the same establishment that bullsh*tted entire world about nonexistent WMDs is telling us that there is a genocide in China despite the UN and every single muslim majority country that investigated the situation say no, there isn't.
One of the reasons why Anglo-America has been turned into such a hellhole is because you Angloamerican denizens have a great propensity to believe any lie that appeases your biases.
But hey. In the recent years, especially during the Brexit debacle, we have seen that a large segment of Anglo-American denizens try to bullsh*t the reality out of existence in the face of uncomfortable situations and especially when facing the failings of their own society. Much better to smear everyone else and feel that you are 'doing okay' than face the music. So, don't let me disturb your cognitive escape. Suit yourself.
