The criticism is shaming. That's the point of the article, that's the argument made for several thousand words, that's the experience much of society faces. More than that, the point of the article is that it's unhelpful, it's devoid of empathy and it's a society-wide problem that vast swaths of society refuse to acknowledge as a problem.
Much like you, right here, are doing.
I'm gonna share a little secret with you. I'm not fat. Not by any standard other than BMI. My belly has not protruded my chest or my waist in twenty five fucking years. But I have been counting calories for fifteen years now, have spent years dealing with bulimia and have a deeply troubled self-image because furries and fat people are the two groups we're still allowed to shame.
And it's fucking bullshit.
This entire fucking page is fucking bullshit because everyone who has never had a weight problem is loudly proclaiming they've never had a weight problem because they're virtuous. Thereby announcing to the rest of us that, as always, we are lesser human beings. And you don't see it that way because you've never been in the outgroup.
