While the transgender question may be an interesting social phenomenon, does it have - and should it have - any bearing on the quality and judgment of the performance?
The best answer is probably just no, but I wonder from sort of a reverse view: How her performing in earlier years might have been adversely affected by the ongoing personal conflict.
I wasn't aware of this until just now, when I noticed the article in the Times. But I had read a lot about 'David' in Joseph Horowitz's book "The Ivory Trade," about the Cliburn competitions. David was in that competition a couple of times, and while I don't remember details, he was regarded as a possible winner, especially when he returned for his second try, but had a very disappointing result, not even making it past the 1st round. Of course this doesn't necessarily mean anything, but this was one of the outcomes that seemed to jump out from the book -- it's the only such thing from the entire book that stuck in my mind in such a way -- and I find it natural to at least wonder. I'll find it interesting to go back and re-read about it.
