These ads above are not interracial advertising, they are interracial propaganda and are often quite repulsive. Someone is consciously pushing this particular group onto society, even though most people don't want it. Hispanics are the biggest minority group in the US but you don't see them f orced down our throats in virtually every ad and tv show. Neither are asians who are also significant in number.
Also notice how in ads "they" are all are intelligent, educated and speak well and live in solidly middle-class homes? Can tell you it sure ain't like that where I live, or the many places that I've been to. You see the same thing in TV shows. They are all team-heads, heads of departments, judges, attorneys, etc etc. Just so fake and so corny.
