I'm gonna do a hit-and-run here...
"Integration" is a tricky word, and in the sense of, if a non-black person has the credentials, the drive, the heart, the mesh to feel comfortable and be an assest to a HBGLO, go for it. And the same vice-versa. If a non-white person has the credentials, drive, heart, and mesh to feel comfortable and be an asset to a HWGLO, they should be able to go for that and get a fair shake, too.
I don't think that we should all join hands and sing kumbaya and strive to have all races equally distributed between all GLOs, because that's the way the world should be... politically incorrect as this may be, it's true that cultural differences exist, and instead of trying to blot them out and homogenize the world, we should embrace and respect those differences. Different systems have different setups, different needs, ask different things of their members. We should be so lucky that there's something for everyone in the GLO universe.
nice topic. this should be interesting. i'm off for the summer and bored as all
