So, in season 20, we see Eric Cartman wearing a shirt with the slogan Token's life matters:
After some quick research I found that this refers to the black life matters movement.
So I get the joke, they replaced the black with token, proving that he is even a racist when he tries to change and give an anti-racist statement.
But I don't understand why Eric is wearing the shirt? What does he want to express with this message? Did I miss an explanation in the episode? Or is this only a litte joke they included without any context to the rest of the story?
