Problem is that in the past two decades university admins gave in to various deplatforming causes and enforced codes. If they had stood firm before, the arguments against them wouldn't be nearly as strong. Unfortunately, they didn't. So when they now use the "free speech" argument themselves it rings hollow.

Those policies were designed to promote free speech from vulnerable groups. Political vulnerability has a huge influence on free speech (and freedom), and that's what they have been addressing.

(Picking two random groups:) If you are Pakistani and are in a room of all Indian people, and the others say how horrible Pakistanis are and how research shows that Pakistanis are less intelligent or prone to violence, that is a very intimidating atmosphere and it would be hard to endure, much less speak up.

If that one Pakistani says the same about Indians, it's obnoxious and annoying, but it's no threat to anyone. The many Indians are not vulnerable. That's the difference.

Furthermore, the dominant groups in a culture tend to create systems and knowledge that support them to the exclusion of others - sometimes explicitly and intentionally. That's systemic discrimination - the system naturally generates it if you follow the usual path. It takes some effort to create space for other points of view.

Whether the typical DEI policies are optimal is another question. I haven't heard anyone come up with a great solution. Some pretend it's not a problem and there is no prejudice, which is absurd and not a solution; it's just sticking one's head in the sand - because they can, because they are not vulnerable.

No it doesn't ring hallow. It is just that the issue is old.
