I disagree. It has only been a generation and a half since discrimination was law (the sixties). It takes awhile to get over something like that. I didn't notice the possible racism in the ad until it was pointed out to me, but I definitely see why the imagery would be seen that way.
When I was growing up (the seventies), I seem to remember a popular argument that blacks are better at physical activity because they don't have the mental capacity of a white man (paraphrased, but definitely implied). Hence, the large number of blacks that flooded into athletics instead of academia after they got their civil rights. Of course, later (in the eighties), the argument changed to "blacks from the ghetto are better at athletics because, in the ghetto, there aren't any opportunities for smart blacks, while basketball or other sports like running gave you a chance out, no matter how small".
Remember that you only have to be in your forties or fifties to remember when you weren't allowed to go through the front door of a restaurant because you were black, your school had no books, and you couldn't walk through the white neighborhood to get to school. Only until the people who perpetuated and suffered from discrimination are gone will the issue be truly foreign to our nation.
