In response to your question about people with Chinese roots...
...You can still enjoy/respect/practice tradition and join Asian American Greek organizations. I really don't see how they conflict. Sure, NPC/NIC orgs are almost always older, but that doesn't mean they fit the individual.
The reality is from 1926-1980 (I am not including Rho Psi because after its first few chapters it didn't really sustain collegiate membership and today isn't a fraternity any more), 12 organizations with APIA focus were created having 13 total chapters. From 1980 to the present date, over 50 organizations have been established, with over 415 chapters having been established. That's an INSANE growth rate. Yes, you can point to immigration...but then the question is, why are predominantly SECOND generation Asian American youth joining/STARTING these organizations? What is it about the system that they saw that they didn't like or felt didn't fit their needs?
Clearly, if they prefered the status quo, you wouldn't have this immense growth that is visible over the past 25 years (primarily over the last 15 though). You wouldn't have kids saying "I like the idea of the fraternal system, but it doesn't meet my needs as an Asian American or provide a place where Asian culture and values can be focused on" or some semblance there of.
The numbers don't lie. There is a need, and there will continue to be a need as long as a) NPC/NIC orgs maintain their cultural "neutrality" and b) as long as there are differences in the way people are treated/perceived based on their race/ethnicity.
Additionally, due to the high increase of the minority populations in this country, I think NPC/NIC organizations are going to take a serious hit(or maybe just become more codensed...who knows it's only a guess) if they don't stop the "we care about all cultures" crap that is preached but in reality is rarely followed through upon.
If NPC/NIC organizations, as National entities (NOT chapters because I know of chapters that are aware), don't educate their members about cultural issues and really develop cultural understanding, it's going to further the divisions. On the same note, if NPHC, NALFO, Asian Greeks don't do the same thing, it will ALSO increase divisions.
The reality is, that as historically white organizations who have memberships that are predominantly white, they have more social capital than minorities just by being white. The same goes for men over women, straight over gay, protestant over everything else, etc. We live in a country (like all countries) that has a power structure. The rules of the game and how the power is distributed favor straight W.A.S.P. men above anyone else. Therefore, because of this, organizations that don't cater to straight W.A.S.P. men are going to exist in order to help balance that power and provide opportunities for advancement where the society as a whole does not do it as well.
Sorry for the long winded reply. It's kind of theoretical, but I can explain further if anyone cares or wants me to.
