This is the -exact- reason why Western idols don't capture the appeal of Japanese idols. While the latter's obsessive fans can be a spectacle in their own right, the general idea behind an idol is they're supposed to make people smile, which is why they prioritise bringing joy to their fans rather than preaching about hot-button topics. A fat chick crying about "fatphobia" is the complete opposite of that.
Modern, Western 'tolerance' simply doesn't work in the entertainment industry, because no amount of equality points will make an unpleasant, miserable bitch entertaining to a wider audience. The kind of people bitching at Pippa and Nyaru over this clearly don't have the looks or the personality to be an idol, and would rather shift the blame than attempt to find other strengths to focus on.
EDIT: They're definitely seething about the stream in a group chat somewhere lmao
