I am slightly uncomfortable with saying this, because I realise there's a lot of emotions around weight:
NO ONE should be made to feel ashamed about their body or weight.
However, there's a fascinating militant movement on Mumsnet of people who are above average BMI, who want to shout to everyone that they are fabulous and that any criticism of anything is pig ignorance, despite them starting a topic inviting people to critique a look, outfit, or even asking for advice about their weight.
I think the body positive movement is fantastic in terms of self esteem. I have of course however fallen foul many a time in my workplace, in so called 'friendship' groups, of people who believe that a tall woman in their mid-40s who runs every week shouldn't be a healthy size 10 , that I "need meat on my bones", that I "need to eat a burger", that "aren't you the lucky one" etc
Many people who self proclaim as size 12 to 20 on here do not countenance any feedback whatsoever, and are so very quick to verbally slap anyone down who wants to talk objectively.
Its why I completely steer clear of any discussions about weight any more. I realise of course that I am now in the "undesirable" camp, but it fascinates me how the sightlines have changes, we can't see anything the same way any more and it has to be a collective rejection of former aesthetics.
