And I am not even obese! So I can't imagine how someone struggling with obesity would feel.
For me, it's the same thing that triggers me every. damn. time. one of these posts comes up. It's a dismissal and denial of the feelings of people actually affected. It's a refusal to employ any sensitivity in the discussion. I don't know the word for it, because it's not gaslighting (that's more deliberate) but it's akin to gaslighting. And it's fucking bullshit.
To be completely fair, the OP of that post has been responding to some people in good faith, so this is NOT a call out post to them. It's just something I noticed in the comments there, but also every time a controversial issue comes up. Like, okay, we don't all have to agree, but can we have SOME sensitivity, SOME deference to lived experience please?
