I think Stephen Hawking has plenty else to be 'angry' about than metaphysical sophistry.
I attended a Hawking lecture some years ago, which he replayed from a laptop computer. This was early days for that, maybe the 90's , so I'm not sure what kind of device it was, but something like that. He actually took questions and composed short answers while the audience hummed quietly. Then when he played each one, the audience became instantly attentive. Very interesting and even touching, I thought.
In the lecture though, there was a treatment of the classic "astronaut falling into a black hole", and I thought that the vivid description of the sundering and rendering of the doomed astronaut went a little beyond what one might have expected.
