In response to the title :
To me, nothing. She's shown her true colours now, and if that's who she is-- I have always tried my best to avoid such people in my life. Respect lost over sad social choices is near impossible to earn back.
But it was the last straw really, I'd lost some gradually over the past 20 years already, so, I am not the best measure here perhaps.
Also, there are so many wonderful people in the world AS well as wonderful artists, leisure and music life's chock-full plenty without her.
