That's a good point. However, say we lived in a mostly obese world (90% and up). There'd probably be "thin fetishists" (also called humans) who would seek out the thin people. If I was a thin person who got fetish messages in this sense, I would be more than a little creeped out and uncomfortable. HOWEVER - if I was avoiding thin fetish messages, I wouldn't post selfies with captions that seem to fetishize my body - "look you can see my ribs, look at my belly, it's so flat!" Because that's attracting what I don't want. So why post pictures of your rolls in a bikini with a caption combining any of the words "jiggle, cut  450a  e, soft, squisy, tummy, etc." and then get angry when porn blogs come after you?  I have a couple theories: firstly, what you said I believe to be true. Secondly, they have this urge to fight and protest other useless things, such as Donald Trump being president, or the patriarchy, or thin privilege. But you can't run around at protests waving signs all day, so maybe it's another way to get their drama/anger fix.  Porn blogs better not reblog this >:(  (Porn blog reblogs a pic of a fat chick in a bikini with a caption glorifying her body)  I said no! REEEEEE!!!!
