I feel the same, her "I Weigh" Instagram idea was good to begin with, definitely embrace women not being seen as objects or to be categorized by their size.
However as someone with Eczema and thus red blotchy skin, having something to cover up on the bad days is not a bad thing, and definitely not a move to objectify myself, or imprison myself.
I definitely find she is too quick to shame people for wanting to enhance their bodies, or use makeup. Her tone suggests she truly believes she is 100% correct and that she speaks for all women. I quite liked Zoe London's tweet on the matter today, where she was saying how people with skin conditions might welcome the new product, and that Jameela seems to think everything in the beauty industry is out to get her.
Whilst some of her past points have been important, she's quickly giving herself an online impression that she is just ranting; this is starting to have the effect that people will not take her seriously. Shouting the loudest at every passing cloud is not going to be helpful. Choose your battles.
