I'm combining my replies to both your comments here, because I'm finding it a bit hard to do them separately - hope that's all right.
Re: Agents of Atlas - it looks like between this comment and the other you read my comments about the colonialist stuff about Venus and the African tribes, right? (They weren't Wakandans; there was a Wakandan anthropologist on site.) To which I would add, you're right that "bad" English doesn't automatically indicate low intelligence, certainly not in real life. But in media, that's often what it connotes when the characters speaking "bad" English are characters of color - especially when the bad English isn't just a matter of using "ain't" instead of "isn't" but dropping descriptors and using "fathers" instead of "generations."
These are classic primitivist stereotypes, and like I said below - according to the plot, they shouldn't be there! There's no reason for a Wakandan device to translate [native word for generation, which in other contexts does mean father] to [English word for father] except that it plays into Jeff Parker's unthinking stereotypes about the noble savage. Now, I'm not going to rag on him too hard for this one incident, because we get these stereotypes shoved down our throats from the moment we're put down in front of a tv ... I didn't even notice that particular element of the colonialist!wtf until my second read-through, so I'm not claiming to be inured. But that doesn't make it right, or mean it shouldn't be pointed out.
Back to this comic: I think we disagree on whether this is undeniable or not, but okay. I can definitely respect feeling the need to learn and shut up rather than trample over other people, since that's often the place where I feel I am right now, too - I'm not white but I come from a different background than most English-speaking PoC, so I sometimes have a very different perspective on things. It's a delicate balance, though, because I think it's also very important to speak up, because PoC need allies.
As for what Jeff Parker should do, I think Kali's answer was really good. To that I would add, he has a blog. So if I were him, I would write a brief entry about my earlier work, stating that I realize now it was offensive and that I apologize for causing that offense. Perhaps a little bit more on the reading I planned to do and assurances that I'd work to do better in the future. It wouldn't have to be long or dramatic or anything.
Mind you, I am certainly not Jeff Parker, but if I ever made a mistake like that in a hypothetical career as a writer, that's probably how I'd try to make amends.
Final aside: Alan Moore and Kevin O'Neill are certainly not Frank Miller, but I was really not thrilled with The Black Dossier: the Golliwog wasn't making any clever statements about race in the 19th or 20th century; it was the creators trying to be clever, and forgetting that there are still kids who grew up with the damn things twisting their ideas about race. Aaaand that's all I have to say about that.
