From her website:
It seems like every week or two I’m shocked to discover another brilliant, creative mind has been hijacked by nonsense. This one was inspired by a musician who I recently learned has become something of a right-wing nut, but it could be about a number of people. I’m not naming names; I will leave that to commenters! Annoyingly, whenever this happens, the formerly sane public figure tends to become even more outspoken, which leads to a social media backlash, which leads to the public figure becoming even angrier and more defensive in a doom spiral of lunacy.
sigh... maybe give-up on celebrity worshipping and focus on what people do: how they make the world a better place. This could be your neighbor, friend, family member, etc.
