The first stage of censorship is to ban any mention of censorship. Just ask the good politically correct folks over at UW-Milwaukee who have forbidden any mention of their system of political censorship.
The University of Wisconsin-Milwaukee recently warned students not to use the phrase “politically correct,” which it said “has become a way to deflect, say that people are being too ‘sensitive’ and police language,” adding that it is “disconnected from authentic understanding of impact.”
And, it is also a critique of the entire system of telling people what to say and what to think.
