I actually sympathise with Stephen Fry. I never understood the appeal of dancing. It was just a bunch of people moving in stupid ways to music. On the very rare occasions that I was persuaded to join in, I felt extremely self conscious and awkward - which only increased as others tried to encourage me further. The sense of bewilderment and isolation I felt watching it and not getting it, was only enhanced by trying it and still not getting it. It aggravated, and made me painfully aware of a pre-existing poor self image that I desperately wanted to hide from.
From what I've read of him, I would guess that Stephen Fry's attitude to dance is just a way of protecting himself. Shanazel is only giving back what Mr.Fry is so liberal with himself. I don't pity him or feel sorry for him. I just think he needs to deal with it. And if he doesn't want to deal with it, then shut up about it.
