That's the gist of it, yeah. Kind of like how it's ok for black folks to say the dreaded n-word but whitey can't. It's intersectional, I'll betcha. I think the guiding theory is that the "oppressed" class can say and do whatever the fuck it wants while the "oppressors" better watch their mouths or there gonna be trouble. Thin oppresses fat by the mere dint of its existence so you can see where this is going. Trust me, I'm a trans-cyborg-wolfkin from the 27th century. I know all about being oppressed.
