Using the term 'boy' to refer to a black man is a well known American slur that references slavery days.

I find it hard to believe you are not aware of this, but I'm willing to accept it wasn't your intention. Fair enough.

Oh, okay. I think I've seen references to that before, sorry for the misunderstanding. I admit it doesn't quite click with me as I am so use to demeaning references used during my generation that to me seem so harsh that it makes you forget how others related in history back then. I would imagine it to be like a post traumatic analogy...your mind pulls forward the worse of what you experience/see/hear.
