They remain predominantly white nationally, just like the NPHC sororities and NALFO sororities are still "predominantly" regardless of how diverse a small amount of chapters are.

"Predominantly" is about demographics and not organizational foundation. Why should demographics be the theme for NPHC and NALFO sororities but "traditional and recruitment" is the theme for NPC and "...based in...." is the theme for NMGC. That's inconsistent.
