I think BGLO orgs sometimes bring segregation in when there isn't any. For example at my school we always ask several BGLOs to participate in Greek Week and they never do. That's so sad
. At my school there is an NPHC fraternity that is the 1st BGLO to have a house on fraternity and sorority row. I see this as integration. If they separate themselves from NPC/IFC greeks then this is what causes segregation.
