I think that if oldu would expand his scope of sororities beyond Chi Omega, then yes, his threads would evolve with a different tone. No disrespect to Chi O.
Since his research focuses on greek life, then he either should include all GLOs - NPHC, NPC, IFC, NIC, MCGLO, NAFLO, and locals (sorry if I forgot one),
OR he should do as others have suggested and specifically state which group / council he is referring to in the title. I mean, some of his titles seem open-ended, so people will infer different things from them.
And just to state, I don't think my NPHC SisterGreeks have hurt feelings from what oldu posts. I don't. I just think they want to get him and others to realize that there is more out there with respect to greek life than just one or two groups. I would think that if oldu's research is truly exhaustive, then he would easily see that.
