Undoubtedly, fat white women comprise a large portion of the "everyone is beautiful" movement, an unfortunate consequence of the modern processed diet with mothers increasingly absent from the home. But the popular notion that media should celebrate "different body types" assuredly comes from multiculturalism, as blacks and Latino women have naturally more pronounced physical features than their white counterparts. This popular insistence that "real women have curves" does for black and Latino women what the exportation of ghetto culture, such as rap, the dozens, and breakdancing, does for blacks as a whole. In sum, by pushing as an attractive aesthetic the fat black girl and big-assed Latino woman or the features common amongst these groups, media normalizes a minority culture at odds with the majority.
As a society, we keep having "plus-sized" models pushed down our throats because in doing so, black and Latino women can have their collective status raised. I've made a similar argument regarding black pathology, avering the notion that liberalism is a social means of protecting blacks from criticism. If we excuse or normalize single motherhood, welfare, and drug abuse, then blacks don't look so bad anymore. Of course, obese white women get to reap the benefits, but the initial goal of "fat acceptance" and "all bodies are beautiful" was to make non-white women desirable. A fact further substantiated by looking at feminist blogrolls. Not entirely relevant, but how else do you explain this?
Ironically though, the most prominent celebrities, pun intended, with black and Latino curviness look nothing like the typical black hoodrat or Latino chola. Here's a slideshow of women with the "curvy" aesthetic pushed in recent years. It includes Jennifer Lopez, Beyonce, Selma Hayek, Rihanna, and Eva Longoria. And of course, perhaps the most hated women in black America - Kim Kardashian. All these women may have "dat ass" and ample curves, but they all have flat stomachs and extremely well proportioned bodies with little fat outside their breasts, butts, and hips. Here's Kim Kardashian, who has apparently ushered in a new beauty standard (LSFW: bikini):
I'm sorry, but what's so different between her and the "unrealistic" beauty standard? I see an almost ideal hourglass shape. How about another "curvy" superstar who is somehow widening the previously excessively narrow beauty archetype:
Now take a look at the hotties who we're told should "love themselves", "be happy in their own skin", and "appreciate their curves." Tell me if you notice any difference. (NSFW and while eating)

Implicit to campaigns like Dove's Real Beauty and "Every Body is Beautiful" and opposition to an objective beauty standard is the idea that the individuals above are equal in attractiveness to Kardashian and Johansen. If we're all beautiful and no hierarchy of beauty exists, then the two groups are essentially equal in beauty. Now you tell me: do black and Latina celebrities like JLo and Beyonce, in addition to curvy white women like above, reflect the type of "real, big, beautiful black" woman shown? The media apparently thinks so, as these recent black and Latina celebrities have been championed as revolutionary in terms of portrayals of beauty.* True Life is a sporadic one-hour documentary series that has been running on MTV since the late 90s. If you want a up-close, firsthand look at this generation's decay, this is the show to watch.
** I don't have any particular animus against fat people; actually I feel some pity towards them. And I even understand why they go to great lengths to fool themselves into feeling good. My problem: don't get mad at society when we reject you as unattractive due to your corpulence.
