I do my best not to play the "I'm a parent" card, but y'all will have to indulge me for a moment.
This "I can be a fatass and still be healthy and beautiful" shit infuriates me. As the father of a daughter I recognize that there are probably going to be body image issues down the line. In my observation, this is very nearly ubiquitous, albeit to varying degrees. Hopefully, it won't be eating disorders and shame, but there are going to be insecurities. This isn't a uniquely female thing, but it's certainly more common among young women (I don't think it's a coincidence that these HAES people are seemingly always women).
My job, and possibly to a greater extent, her mother's job, is to teach my daughter to be healthy and embrace who she is, rather than believe she ought to be able to look like the .001% of women society tells her are paragons of beauty. I also have to teach her that her real value isn't her body or looks. This was going to be hard enough as at was, but now I have fatass sows on the other side telling my kids that it's okay, even healthy and beautiful, to be fat and/or obese. It's not, and allowing my child to believe that is no healthier than teaching her she ought to starve herself to look like a runway model.
So now, rather than simply finding a way to teach my daughter to love what she has, I have to find a way to say, "you don't have to be rail thin to be beautiful" while also explaining why being fat is also bad. Then I have to explain why not being fat is a deeper issue than mere vanity, and that she needs to be a healthy weight not just for beauty but for health. I also have to do this without sounding contradictory, which is going to be a fine line, especially to the ears of a teenage girl.
So, thanks, obese land whales, you've contributed to further pain and insecurity among young women and their parents, and you've done so solely because you're too fucking weak to take some responsibility for your weight.
