Ha! It makes it sound like you're saying that young black kids are self-important dickheads and that's why he's a good role model.
But, yeah, I know what you're trying to say. Despite his social media presence, the image that kids generally see is a very positive one. He's a somewhat stylish (in his own way) guy, who clearly has personality, and is a very accomplished scientist. I just cringe any time he comments on something not related to astrophysics.
