Earlier quoted context omitted.
To keep the parent comment honest, the word "Mao" doesn't appear once in this article; and in fact, near the top they use McCarthyism as an example of the type of "indignity" spoken of. Why a phenomenon identified in western society in the article needs to be made into some jab at maoists is beyond me though.
It's because the current illiberal bias on the university campus comes from the left so folks on the right are tying it to Maoism. Thanks for flagging that McCarthy mention though because this type of illiberalism can certainly come from either direction
Sincerely, much respect.
