From my perspective, I think this thread (compared to others on tattle esp) does not seriously or maliciously body shame or fat shame EDL. Also as someone with child-bearing hips lol I think this thread doesn't really cross that line.
I think what this thread is satirising is that EDL chooses to edit/photoshop that pear-shaped figure to the nth degree and removing any evidence of it altogether. This altering gives a false impression to a lot of impressionable young girls that our type of figure isn't ok and like she's ashamed of it, when the irony of it all is that her instagram figure doesn't match the reality of her IRL figure, and that's what the thread roasts.
If she turned around and posted her actual body shape, unapologetically, I don't think people here would shame her in the same way as the fakeness of pretending she's not shaped the way she is, and effectively shitting on us child-bearing hips folk in the process.
