In my opinion, the author isn't conveying a "we need diversity" vibe as much as "yay! Happy greek life members, who cares if their ethnicity is not what'd you typically expect."

No overstepping, and I apologize if I seemed accusatory.

I only see NPC chapters not having black members as a problem if they're purposely seeing to it that they don't have them. I'd expect that a typical NPC chapter's membership is a microcosm of the overall campus population, at best. Now if, hypothetically, an NPC chapter had a significant pool of black PNMs at rush consistently over the span of a few years, but its chapter is still superwhite... problem. I wouldn't throw segregation in as an automatic solution, but I'd hope the chapter would at least acknowledge it.

I'd say the same towards a hypothetical NPHC chapter that had an unusually high white interest pool expressing interest but still had an all-black membership. Again, not saying "well, just take X number and we're good" but acknowledge it.

I know what you meant and agree 100%. Each BGLO does whatever it envisions regarding "diversity." That doesn't mean that people (including some people on GC--I recall one thread in particular from the past year) should look at the predominance of "Blackness" in BGLOs and find that problematic based on our history and missions.
