My pet peeve about misuse of capitol letters is with the adjective, "black". I see it too frequently in articles that discuss "Black" people. The word "white" is never capitalized in those articles, unless it's the first word in a sentence and just can't be avoided.
Black is the only color that is a race. Chinese are yellow. But that’s racist. The American Indian is red. That’s racist. White, as in white people, is used to describe evil devils so I’m not sure if it should be capitalized or not.
