I've seen it a few times in the last four months or so - bigger women supposedly ranting racist remarks at someone in a video on Facebook. But guess what: The first of these memes, the fat blond lady sitting next to an African American man and telling the stewardess that she'd like to be moved to another seat, turned out to be false (Snopes).
The second, another fat racist blond lady spouting off against a Muslim kid, appeared on the site Loonwatch, an anti-anti Muslim site. It turns out to be false, as well. It went viral, though.
It seems that people really get into the idea of fat white women being racist. No doubt there are fat white women and skinny white women who are racist, and skinny white men, and fat white men. But there are people who hate fat women so much that they are willing to invent scenarios and memes in which they portray fat women as racists. My god. If they wish to find real instances of racism, whoever voices them, they can, I am sure, locate actual examples.
Or would these examples not be quite as satisfying because they might not feature fat women?
Yet another good reason to move to FatLand. Fat women are not made scapegoats in/of invented racist memes.
