You don’t really explain here how the body positive movement “hinges on” (implying relies on) anti-blackness. Your only claim is that “white people are influenced in EVERYTHING by racism so therefore even if something isn’t specifically about race, and someone isn’t being overtly racist, they must be still being racist somehow because they’re not making every single thing in their lives be about race”.
That doesn’t make sense to me honestly. Also, you assume that everyone online or on Instagram is American, and everyone white has ancestors that owned slaves, and that our “DNA” somehow carries racism within it. Like a stain that we can never erase except by performing continuous guilt as a way of trying to prove “we’re not like those other white women”.
From what I’ve seen of the body positive movement, it’s mostly run by women outside the normative body standards. Fat women, or people who may not be strictly fat, but certainly aren’t thin either. Maybe I don’t spend enough time on Instagram (I don’t actually have Insta and my exposure to this movement is through Youtube, Facebook and blogging), and maybe I’m seeing a different side of the movement than you are, but I don’t see it as an inherently white supremacist, thin-supremacist movement.
And your “jealousy” you feel at seeing women (who happen to be black) own their size and their curves and their sexuality — is that really you being racist? Or is it you being insecure about yourself? Maybe you don’t feel confident in showing your own body that way? The way you described it as “I want what they have” doesn’t seem like you want these women to NOT still have their confidence and following, but more that you wish you were more like them. Which is a good thing, right? That you see these black women as role models for confidence? It’s not “hatred of free black bodies”. I mean, maybe for you it is, cause I don’t live inside your head, but it certainly isn’t this way for everyone or indeed most people.
I don’t deny that white people do have certain levels of ingrained racism and prejudice, even the most well-meaning ones, and that’s definitely something that needs to be addressed. But that doesn’t mean that the body positive movement “hinges on” racism, or that everything white people do, if it’s not explicitly about race, is still somehow harbouring a deep hatred for black people “ingrained in our DNA”.
