>HAES is a reaction that says "What if we accepted that some people are just going to be fat, and then tried to come up with ways of being as healthy as possible given the circumstances". You may not like the packaging that HAES comes wrapped up in, and the most vocal proponents of it are often the least interested in making it palatable to you. But it's not BS.
If that was all it was saying, I'd be onboard.
But it also says things like "losing weight is literally impossible!", and "there is no evidence that obesity is unhealthy!" and then cherry-picks and misconstrues research so that it seems to give scientific backing to those conclusions, which are deeply harmful lies.
