I don't know what to say. It's not a global media conspiracy. For decades there have been actual fat acceptance activists and communities. Good luck.
"Doesn't exist" was hyperbole. If you want to be literal, what the OP was saying is that it's an extremely small fringe group that isn't large enough to matter, and the response to it created by internet outrage culture makes it look like a much bigger issue than it actually is.
Yes that was my intention. Please note that I didn't say "doesn't exist", I said "doesn't really exist", which is not the same.
