I don't buy into it because of the massive health implications.
On one hand I WANT people to care about themselves, to have self esteem and to reject superficiality, stereo types
and preconceived notions of how they should look.
On the other hand, every shift I'm confronted by the results of obesity, high cholesterol, stroke, joint issues, etc, etc with more and more bariatrics presenting for immediate medical interventions.
That being said, the whole "fat is beautiful" IS an issue when it starts to affect health and that person's ability to function in their life in the ways they would wish.
Unfortunately, many abusers justify judging and degrading and bullying larger women based on health argument, but what other poor health choices can be used/are used, to mock, vilify, degrade or attack others and accepted as appropriate?
If a person doesn't like vegetables and chooses not to eat them (and is slim/average size), would it be acceptable for others to single them out, demand they eat vegetables, mock and humiliate them, tell them they are disgusting etc?
We assume that they, as an adult, understand the implications this has on their health, and that their choices are for them to make, and none of our business. We would not dream of forcing our opinion and judgement on them or interfering with their lifestyle choices.
So therefore, whilst I agree the behaviour should not be encouraged, it certainly shouldn't ever be mocked or used as an excuse or justification to make a person feel bad.
Also if you're a health professional, I can tell you, as a large lady, that negative opinion even if a professional and fact based opinion, causes feelings of shame and guilt. Those feelings also continue the cycle behind the root cause of many with weight issues, low self esteem.
Consider how you might speak to and about a lady suffering with anorexia nervosa who is now at a stage where she is at risk and suffering health complications. Would you speak harshly, judgemental, blame placing? Or would you be gentle, compassionate, use empathy, try to understand and examine cause and attempt to help/deal with the emotional issues first?
I realise I've gone somewhat off topic, as was said in the beginning, the first issue is to remove the idea that a woman's value as a human being, is based on physical attractiveness/appearance/size.
I am not disgusting because I'm big nor am I unworthy because I make poor choices for my health or even undeserving of others consideration and compassion just because I may, due to low self esteem and trauma have no consideration for myself.
But if I had to say why I am beautiful, not that I've convinced myself of that yet, it would be because I try every day to treat others kindly, show care, consideration and compassion etc...
Sorry for the essay
