Why are there so many dehumanising memes about fat women as if we're some aberration when a high percentage of the population are overweight or obese?

Lately I've been seeing so many memes or posts making fun of fat people (mostly women), acting almost as if we're some alien species. Jokes about fat women eating people, being compared to animals, being portrayed as completely desperate or s*x-craved, a regretful one might stand, doing unhinged things like having Oreos in their drawers instead of condoms (recent one I saw lol). Yet being overweight is so common— surely these people interact with fat people all the time and can see we're not that different from themselves? Surely they have fat relatives or friends or coworkers in their lives who regularly prove these stereotypes wrong? In daily life I see so many fat people in relationships so I don't really understand why people act as if fat people are inherently unloveable/unfrickable?

Idk it's probably my fault for using Twitter still and interacting with this stuff so the algorithm keeps showing me similar posts. It's just depressing as heck to be constantly viewed as a disgusting joke and makes me wonder how many people I interact with irl share this kind of sentiment
