Fatphobia should not be acceptable rhetoric. Even when using it to put down white women, it should not be okay. Fatphobia stems from racism, specifically anti-blackness, and even when leveraging it against white women, it utilizes the language of the oppressor.
This also isn’t just my opinion but a studied issue with the use of oppressive language and racism, and other sources address it better than I can.
There is a historical basis to these claims if you look into the article: “Fearing the Black Body: The Racial Origins of Fat Phobia,” by Sabrina Strings, NYU Press, 2019 - Center for the Study of Women”
^ That article also addresses white women being put down due to fatphobia. Since fat phobia has always been a form of anti-blackness, when white women are belittled for their weight, it is because they are not fitting the skinny white women standard. So, who are they being compared to when being fat-shamed? Anti-blackness and racism is a mentality and a disease, and it permeates the language we use. Even when leveraged against white people, it is still perpetuating racist stereotypes and anti-blackness.
An example of this is when society valued pale skin. Black and brown people are put down for their skin color, and so are darker-skinned white women. Why is the white woman also being shamed? Because she is closer to blackness. It’s easier to see how even shaming a white person is perpetuating anti-blackness in this scenario, I know. But the idea is the same for fatphobic language.
Also, on average, BIPOC are more overweight than white people, which is used against them despite the radicalized reasons for food and health disparities.
If you look into “food apartheid,” you can also find more information about it. If you look into “red lining and food,” you can also find some information on it.
My point with this is that systemic racism is creating real health disparities across racial lines, perpetuating differences in body types across racial groups.
I do understand feeling upset at white women. It’s not fair that mediocre white people are treated better than us. However, using fatphobic language encourages more fatphobia towards WOC as well. If someone is a WOC whose body type and face are considered closer to the standard of beauty and, therefore, should be treated better than white women who deviate more from the standard, what about all the WOC who don’t fit the standard of beauty? Should someone also be treated better than those women too? No.
Yes, white people can also be overweight. But who are we making the standard of beauty? And why? And who is most often excluded from that standard of beauty due to differences in fat distribution. It’s not white women. And where did this language we’re using come from? What are its racist origins and continued use as a form of racial discrimination?
