I've not seen it although there's millions of threads it may well have happened.
And they are stating how they feel? The judgement on women's bodies and society is huge and starts young. Girls and women are essentially encouraged to feel shit about how they look. Even if they look fine/ good.
Eating disorders are rife.
If that's how someone feels it's how they feel and it's not (I imagine) done to upset anyone. But to express their own unhappiness.
So try and take it in that spirit?
Just thought of an example. I have big scars (not on face but visible). At school a girl hurt herself and I walked in and she was showing a tiny scar to people in a less obvious place and described it as disfiguring and said she would obviously get plastic surgery.
At least she looked a bit sheepish when she saw me.
On the telly all the time there are things about 'imperfections' - blemishes scarring whatever. Tiny trivial things and how to disguise them as OBVIOUSLY (unspoken) they are unsightly.
After that first school thing I just let it wash over me. They aren't making a judgement on me, it's not personal. It's their own insecurity, how they feel about themselves. And given how trivial it often is I feel a bit sad for them iyswim.
