The white cop/black man shooting problem. The problem that, although it doesn't affect US (you and me), is still a problem. Your dislike for Kaepernick and others like him (Lebron, etc) is apparent. I personally don't hold Kaepernick's outspoken-ness against him. In Lebron's case, he's mouthing off about a global issue that is really none of his concern, regardless of NBA's ties or derived benefits from China. It's not his case to plead.
Terrell Owens was all about Terrell Owens. Now THAT'S a "me, me, me" guy now that you mention it. I don't group those three together.
