Drawing support from a recent OpEd piece by Harvard Law professor Randall Kennedy, the text raises legitimate concerns about certain DEI policies enforcing ideological conformity, yet its dismissal of the entire DEI enterprise as universally antithetical to true diversity and inclusion relies on the fallacious overapplication of those specific criticisms to all such efforts across academia.

1. sweeping generalization The author seems to make a sweeping generalization while accusing DEI advocates of employing a motte-and-bailey fallacy:

DEI policies on campus and the infrastructure created to perpetuate them -- including mandatory diversity statements -- fly under a false flag. Instead of diversity, they promote a rigid ideological uniformity. Instead of equity, they advocate inequity in the treatment of political minorities.

The "motte" or easily defensible position would be the stated goals of promoting diversity, equity, and inclusion, which are laudable aims that are difficult to argue against directly.

However, the "bailey" or indefensible position being conflated, according to the author's perspective, is that the actual implementation and requirements around DEI policies like mandatory diversity statements promote the opposite - enforced ideological conformity, inequity towards political minorities, and exclusion of dissenting views.

Characterizing the rhetoric of some DEI programs as a form of the motte-and-bailey fallacy could be a valid criticism. Some DEI advocates put forth the motte of lofty diversity goals, but in practice operate from the indefensible bailey of the author's critiques.

However, not all college DEI programs may be guilty of such a tactic, in which case the author could be guilty of a sweeping generalization about DEI programs. There is likely nuance and variation in how different institutions and DEI initiatives actually put their stated goals into practice. To claim they universally promote the opposite of diversity, equity and inclusion is likely an overgeneralization.

Unless the author has systematically analyzed the implementation of every single DEI program, it would be a fallacy to make such sweeping claims about all of them based on specific criticisms of how the rhetoric around some programs does not match the reality. The author could have guarded against this by inserting the word "some" at the start of the quote above.
