First off, I’m a white guy.
Most people I know, black and white, use “black” in casual conversation when referring to those whose can trace their ancestry back to central Africa.
In writing, I tend to bounce back and forth between “black” and “African-American.” If I’m writing about something that addresses only blacks, I’ll use “African-American.” If it’s regarding both the melanin-enhanced and melanin-challenged, I use “black” and “white.”
Those using “people of color” tend to be whites whose political orientation is far left of center, and females more often than not.
I found that locally newspapers catering to a city’s black population capitalize racial designations, using “Black” and “White” instead of “black” and “white.”
In Buffalo, the term “colored” is still in common usage among many Polish-Americans and older ethnics. What’s an “ethnic?” In Buffalo, it was someone who is Polish, Italian or Irish. If you’re white but of English, German, Swedish or French heritage, you aren’t “ethnic.”
Blacks don’t live in “neighborhoods.” They live in “communities.” It’s supposedly impolite to refer to a “black neighborhood,” because it sounds one step removed from “ghetto.” I grew up in a part of Buffalo called Kensington. As the area’s population changed from predominantly white to predominantly black, the media and local officials stopped referring to “the Kensington neighborhood” and instead referred to “the Kensington community.” Buffalo’s East Side is not a collection of “black neighborhoods,” but rather “black communities.”
New Mexico didn’t have a large black population. When I lived there, whites weren’t “white” … nobody used the term. Folks were divided into one of two camps, “Anglo” and “Hispanic.” Hispanics didn’t think of themselves as “white,” but they were Causacian.
Recently I’ve been told that “Hispanic” is now considered offensive, and that the polite term to refer to those who can trace their heritage to Spanish-speaking countries in North and South America is “Latino.” Why is “Hispanic” offensive? Because the term was supposedly coined by Anglos; it has a fairly sharp, blunt sound about it that seems naturally derogatory in tone, and the word rhymes with “spic.” Really.
I give up.
