Yeah, there'll be a lot of discussion of gender and triggering and the rest in social studies departments, but to regard that as reflective, never mind representative, of higher education as a whole is ludicrous. Of course, a disproportionate number of politicians and journalists come from such departments, and rather fewer from Condensed Matter Physics, so they think that universities are in constant ferment about these topics. They really aren't.
Whether universities are in constant ferment about these topics isn't the point. What is at stake is whether is it is possible to put forward views that challenge orthodoxies that have emerged from disciplines such as sociology which do deal with these topics (and which do have significant impact on society more broadly). And, in that regard, I agree with Sam Gyimah. Try saying that women don't have pensises on a university campus these days. You won't lose your job (academic freedom), but you will find yourself the subject of a witch hunt by a baying mob from the SU, some of whom will call for you to be sacked, and shout abuse at you. Some of your academic colleagues will also not be above such tactics.
