I thought I read GKP analyzing the phrase as an attempt to defuse or skirt (2), and supporting that goal in principle. I didn't see him getting around to explaining why he didn't like the phrase despite claimed support of the goal....
My first gloss of the phrase "practitioner of diversity" in the first quote was indeed along the lines of "someone who works at promoting diversity," but I bought the later argument about unqualified "practitioner" being fairly normal lawyer-speak. I mostly find the usage confusing, as diversity seems like a property of groups, not individuals, so I came up with the wrong reading on the first pass. I wonder why something like 'underrepresented" doesn't serve the purpose.
