Okay, I came here hoping to talk a little bit about the show and find a shouting match about who on this site is more racist.
Look, even before I came here I noticed that as soon as they introduced one black character they killed off the one before. Tyreese replaced Oscar replaced T-Dawg replaced Morgan (dude from the very first episode). It's true. And everyone else except for Glenn is white. Also true. You can understand why some people would think it to be a bit racist.
At the same time, the argument can be made that they are just furthering the plot. You can't expect to go up against walkers and dudes with submachine guns and expect everyone on your team to make it out alive. Someone has to die, but for the sake of the show's narrative it can't be the biggest characters. The lesser characters have to die. Perhaps it's racist that all the black people on the show are lesser characters. But the main reason they're dying is because SOMEONE has to, not because they are black.
