If you don't lump them under "white", you'll see they are over-represented on higher positions of the media, tech, government, justice, etc. so it's in their own best interest to be lumped with whites.
On an unrelated note, as a non-American, it's stunning to see how wide those roads are, how big those parkings are, and the amount of SUVs and pickup trucks. I mean, that's kind of the American stereotype, but it calls my attention to see that it's actually true. (Speaking about the last link in particular.)
>Going with the maintainer's repo means that you trust the maintainer with providing security updates for the version you have installed or you trust them with providing a useable upgrade path.
Why should that be a problem if you use the official repo, handled by MongoDB themselves?
