Offensive Shirt Statement

Alright, little cub, listen up. This meme is showing a guy, who has Down syndrome, wearing a shirt with a really bad, hateful word on it. The shirt says, "AT LEAST I'M NOT A NIGGER!" Then, below that, the meme creator added "true enough." The "joke," if you can even call it that, is a messed-up comparison. It suggests that someone might feel better about their own condition (having Down syndrome) by saying they are not a member of a different group that is targeted by this racist slur. And you, my listener, by looking at this, are trying to understand this messed-up logic. It's super offensive and not funny, you big dummy.
