I think women really believe that they can convince men that being fat is attractive.
IMO, one of the most insidious ideas is that there is no such thing as biology or DNA.
The idea itself isn't so bad, as it's just an opinion. But it becomes extremely dangerous when large amounts of people start to believe it.
Meaning girls actually start to believe that female beauty is ONLY due to social conditioning. I would suspect that BILLIONS of women today actually believer that the only thing that makes a woman beautiful is what society thinks, and since society (fashion, movie industry) etc. is run by a certain demographic, it is THOSE PEOPLE who created the "idea" that a certain type is "beautiful."
And the ONLY THING they need to do is create enough social momentum that "fat is beautiful" and so long as enough people believe that, it will become so.
Fat chicks ACTUALLY BELIEVE they can be perceived as naturally and automatically attractive as traditionally gorgeous chicks.
This is idiotic, but the problem is that plenty of women can go either way.
But instead of putting in the effort to get into shape, work on their natural femininity, they eat like hogs and spend all their energy trying to convince others that FAT IS BEAUTIFUL.
And because they can get laid, and get male attention, THEY THINK IT'S WORKING.
They don't realize that most dudes consider banging a fat chick only marginally better than banging their fist.
If you hypnotized the average dude, he'd probably bang a tree stump if he thought it was a sleeping fat chick.
