If you blur out the details, this is a very familiar story about artisrs (here: performers) getting harassed by fans for changing their style. Fans often don't like it when things change, and for pertormers, their appearance is part of their style. Fans railing over change is a well worn truism.
What the details do is try to attribute that everyday story to the hot cultural debate over obesity epidemic and the related normalization of obesity.
But is the story really about that? Or are the fans just doing what fans do?
