That's the thing.  They don't merely want acceptance, they want a right to sex with the thin people they proposition.  We know this becsuse the Buzzfeed clickbait sites, Jezebel feminist clickbait sites, and mombie sites portray said thin people as evil villains for not saying "yes" when their date shows up much fatter than advertised.  This goes for both genders: look at how Caleb Luna and Matthew Rodriguez complain about how thin, attractive guys on Grindr don't want to have sex with them. They'd never have sex with someone who looks as bad as they do.  They're hypocrites who want double standards.    Look at the article titles when googling "fat tinder date."
