Use of present perfect with a set time and unfinished action?

You, guys, are so English! I love it! One must really live in America to understand what it is, what "Black" is. I wouldn't be that categorical as to whether I should never capitalise the word "black" if I choose to describe someone's color.

Black is sometimes capitalized in its racial sense, especially in the African-American press, though the lowercase form is still widely used by authors of all races.

I've capitalized the word "black" meaning the race, not the actual color of the skin.

No they don't. Did they say that sentence? Is the old guy's name Heather?
Sorry, but I don't follow your point. If you present your argument in a more traditional way, I might be able to respond sensibly to it.

That statement is by someone from that family. I wonder why no Americans prove me wrong. It just sounds right to me. It sounds so Hollywood, so New York.

I live in a place where people routinely say "I've went" so I'm sure there are Americans who say "He's been gone to X since Y" but I call it utterly non-standard. I would definitely edit in writing and correct my children if they said it.
