The fat acceptance movement — while it had noble goals at first — has now become a ridiculous, anti-scientific parody of itself, not much different than the anti-vaxxers.
According to the mainstream of that movement, caloric intake has nothing at all to do with weight and fat is all some “genetic virus thyroid” problem not just plain old gluttonous overeating.
So every time I see a link to an article about Marilyn Monroe being in actuality very petite (as she was), I link to it.
As a direct example of her size, the white dress she wore in The Seven Year Itch was recently auctioned off and was put on a mannequin that was a size 2, but they were still unable to zip up the dress as the mannequin was too big.
So further to the fact that Rubens’ models were anomalous in Western art, Marilyn Monroe was tiny.
Self-justification for poor self-control and lack of ability to even deal with basic facts of the universe doesn’t make me have sympathy for a movement, and the FA movement has gone completely off the rails to the extent that it was ever on them to begin with.
But the FA coalition is very American (there’s almost no such groupings outside North America) — it’s “let’s accept the misery we’re in and proclaim it as right and good” rather than “let’s make ourselves and society better.”
