I'm not quite sure whose social & political beliefs you mean. The audience's? They thought she was affirming *theirs*? Not in that city (i grew up near there). Didn't you hear her read out or refer to a tweet someone had sent her where they said, "You can't say that shit in San Francisco. That would not have been a right wing audience and there were probably a fair number of gays present, considering the strong gay population in SF.

And we weren't hearing approval at the end. I think the (sparse) applause was just sad sympathy for the artist we all know she can be. And earlier on they seem to have thought she was joking.

Or have I picked up your meaning all wrong?
