I think you're misunderstanding what people are saying, and I think many are misunderstanding the story.
Every person is a product of his/her race, culture, background, experiences, etc. Those things define who we are. They give us our identity. It gives me my identity. It gives you your identity. It gives Dak his identity. And from that identity, you relate to people and people relate to you.
This story is not about race but how Dak's background helps him relate to his teammates.
Yes, it's because he's likeable. Yes, it's because he's a leader. Yes, it's because he's relatable. But all of those things are a product of his background, which includes but is not limited to his race.
The stories about his leadership have been done, and I don't know any who have complained. The stories about his likeability have been done, and I don't know any who have complained.
The story about his biracial background has been done, but now some folks get all freaked out about it.
Dak, who answered the reporter's questions on the topic, wasn't freaked about and acknowledged the role is background has played shaping who he is.
If he's not upset, I'll take my cues from him and refrain from getting all bent out of shape about the story.
