I wasn't a fan of Lorraine Hunt Lieberson, but this was due to ignorance rather than hostility.
In the liner notes for this Wigmore Hall recital recording from 1998 is this brief conversation:
"You have one of the most beautiful voices I've ever heard. Who are you?"
"I'm a violist."
One hears the violist in her voice and her music. What one wishes from a singer is to feel that if one merely reached out, one would touch her soul. Lorraine does this on virtually every note.
There is a way she draws back on the tempo, relaxes into that dark mysterious pool that is her voice and reaches heaven.
