Agitators also use PC as a shield to mask regressive agendas. From Radical by Maajid Nawaz:
*"The student affairs manager was a chap called Dave Gomer. He was the point of contact between the college authorities and students. A friendly, affable, well-meaning guy, his politics were forged in an earlier era, a time when student protests were about sit-ins and strikes and occupying the Student Union. To someone of Dave’s generation, student protest was ‘kids being kids’ and a healthy part of someone’s political education. As you can imagine, we ran circles around that man.
Unlike the student protests in the 1960s, by using religion and multiculturalism as a cover, we brought an entirely foreign lexicon to the table. We knowingly presented political demands disguised as religion and multiculturalism, and deliberately labelled any objection to our demands as racism and bigotry".*
FYI - Nawaz was a recruiter for Islamist organisation Hizb-ut-Tahrir. He now runs an anti-Islamism think-tank. Radical is his autobiography.
