I mean, brainwashed HR drones trying to teach DiAngelo's nonsense is one level of problem. But dig deeper, turn over a few more rocks and the structural nature of the problem becomes apparent. It's not just white privilege that's a wrong and harmful idea coming out of universities, there are lots of such ideas, and there is absolutely nothing that can stop it. No mechanisms, no social conventions, nothing. Professors can just make up junk their entire lives and be continuously rewarded for it.
The consensus on Hacker News has always been that we shouldn't, that any attempt to do so is a slippery slope that leads to tyranny, because free speech must be absolute and non-negotiable, regardless of content, truth or consequence. "I may object to what you say, but I will defend to the death your right to say it," is the thought-terminating cliche often employed in the myriad other threads where free speech becomes a topic.
If this thread were about controversial right-wing speech, you would be shouted down as a bigot and a fascist for even suggesting that ideas can be "wrong" and "harmful." You would probably be one of the people doing the shouting down, as you've argued for free speech absolutism in other threads, and against deplatforming, cancel culture and other "leftist" and "SJW" attacks on free speech.
If it's not a problem when it's anti-vaxxers, neo-Nazis, racists or QAnon plotting a coup, it shouldn't be a problem here.
