I imagine the prospect of not having to author Maoist style diversity statements and other indignities will be quite a draw. Universities have become inhospitable and intolerant places for even politically moderate folks.
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.
