The meme is "To learn who rules, find out who you cannot criticize". It's anti-semitism that can get you fired in the USA, put you in jail in Europe.
Criticism of whites and Christians bears rewards, not penalties. Which is why so many are doing the Maoist self examination/self criticism bit.
the only group you can publicly criticize and get away with are whites -- anyone else, Jews, LGBT, blacks, muslims will get you fired. UNLESS it is Jews in Israel and then you are on compoletely safe ground, that is why I put them near the bottom in the green.
