Yes but here's what I think it really is, I think this video is aimed specifically at celebrities, whether they be actors, singers, or just influencers, those who drive the culture. She's been made an example of to them.
This video is tantamount to taking the woman who resists the hardest and loudest in the group and then humiliating her in front of the eyes of all of the other feisty women, so that all the others who would have come out are now too afraid even to venture to say or do anything.
It's not really aimed at lay women on the ground.
I think she was likely got at by her record company and, as has been said upthread, maybe her bandmates are pissed.
But also, the left of politics tends to inhabit the creative industries. So for someone like Macy it's not just backlash from aggrieved fans telling her they used to look up to her and now their entire lives have been ruined because they've discovered she's actually a real person with a mind, and (not just an idol they imbued with their own values) but likely many friends and associates in her circle share TWAW women views and 'Be kind' and are likely guilting and re-educating her too.
I follow a lot of creative people online and they are all, bar a tiny percentage, fully infused with leftist 'embrace everything without discrimination' right think, and even those who aren't, fall afoul of Be Kind. So I can't imagine the social atmosphere in the music industry.
I think anyone famous who wishes to publicly speak a GC view needs to be prepared to walk away from it for at least the short term, or say nothing, because being forced to publicly recant like this so obviously under duress, puts the frighteners on other influential people.
But with reflection, I agree with previous posters it is disgusting she's been broken down like this, especially disgusting to use such tactics on a woman with possible bipolar disorder.
