Everything you have written is true. If you read the comics, I bet you’d have stopped reading a long time ago too as the comics have generally the same character ensemble.
Same can be said for almost every big movie and TV show. I feel we have to keep creating our own TV shows with our own narratives and also start supporting those already on air e.g Power, Empire etc
I consume TWD because of its amazing content as I know the depiction of black men on the screen isn’t necessarily our story in real life.
