I don't think the Black Dude Dies First trope is a thing in the regular Walking Dead.
Yeah because them not dying first makes all the difference. Out of all the black characters who magically happen to still be alive, one was missing for almost the entire series, one doesn't talk, and one is a psycho. Let's not forget about poor Tyrese who bravely died while staring at a picture for 30 minutes, or that other kid who died (I don't remember his name he was only on the show for a few episodes).
