For black CEOs in Silicon Valley, humiliation is a part of doing business

Stylistic question. I noticed Black and White capitalized in this article. Is that an emerging convention?

It's a really interesting story, actually! The question of whether and when to capitalize has been an active one since at least the early 20th century. Here's a (very) recent Columbia Journalism Review article that discusses it from a stylistic perspective:

And I also thought that this article, about the Brookings Institution's decision to capitalize Black in their reports, had some interesting historical context:

Capitalizing White seems extremely weird, though, and somehow emblematic of how we're sliding backwards into a racialized consciousness even while trying (and hopefully succeeding) to step forwards toward equality.

This. The words "white" and "black" are not proper names of places, and they aren't honorifics. To say I'm "White" would be like saying I'm "Fat" or "Tired".
