I would submit that the aforementioned reference to an "interracial kiss" on tv more often than not only reinforces notions of white superiority. This is because more often than not these "barrier breaking" kisses are usually betwenn a white male and a "woman of color". Nothing earth shattering about white males feeling they are entitled to "play" with the non-white women (they're just for fun, while marriage is reserved for white women).
The discourse of race and predjudice is framed from a white-centric point of view. There are whites and "non-whites". The term "race relations" really refers to the degree to which white people are comfortable with the status quo and the degree to which "people of color" keep their mouths shut over that status quo.

I really like this blog, especially the parts about Crash and True Blood, but you overstate the effects of having a superordinate goal. As I'm sure you know, this kind of cooperation only leads to prejudice reduction when certain conditions are met, including, for example, equal status contact and having the cooperation be endorsed by the person(s) in authority. Unfortunately, all too often, the necessary conditions for prejudice reduction are not present in our every-day lives and, if we wait around waiting for them, we are likely to continue to hold whatever prejudices we may have. They key is to actively seek out equal-status experiences with the targets of our prejudice, which as I describe in this blog, is far from easy: http://bit.ly/34qZTs
