Why do multicultural GLOs/organizations exist?

[Taualumna]

If there are multicultural/historically minority organizations on campus as well as NPC/NIC, do you think the latter two would less likely become diverse? Would you think that it is an issue? Is there a way to encourage minorities to go through recruitment at historically white organizations (HWOs)? I'm just asking because many HWOs want to diversify themselves, but often find it difficult.
