Fun story: I went to my first Gencon in 2000 at the age of 16. I dressed up as a drow. Painted every visible part of my body with black paint, and my hair snow white. Had nooooo clue about the history of blackface or minstrelsy. There was nothing more to it in my mind than dressing up as a fantasy character. Stopped at a grocery store on the way to the convention center, and after we left, the friend of the family who was escorting me told me she was taken aside by some pretty angry black people to question my make-up.
Plus, if you want to talk racism: why do we call the people here before that kidfucking piece of shit Columbus indians?
I just did a bit of looking around, and was surprised to find there's still many out there who prefer American Indian over Native American as a blanket term. Mostly out of convenience.
I was looking, because I recently saw a quote from one who claimed he preferred Indian. I couldn't find it again, and I wish I could remember it better. But it was something along the lines of every term having its own issues, but with Indian, at least it has the benefit of preserving the association of their problems, including the terminology problem, with one deplorable white man's colossal fuck-up. I got a kick out of that logic.
