I know this because he consented to an interview with the fanzine author R.H. Drexel, run by Hawk Wakawaka on her blog. Like most of Drexel's work, it's intensely personal and interesting.
It's also the only interview that Parker has granted the "media" this year that I'm aware of. Drexel is not a journalist, but still, Parker wouldn't even grant the interview to Wakawaka, whose expressions of gratitude on her blog to people who talk with her sometimes border on obsequious.
In the wine world we have become accustomed to accepting that Parker doesn't want to face questions about why he gives so many more 100 point scores than he used to, even though other critics would give an answer.
Parker, who is arguably a member of the media himself, might protest that he is like a Hollywood celebrity. Their agents frequently dictate terms for how interviews with them can be conducted -- although once the interview starts, journalists often ask the questions they want to anyway.
Parker has taken the kind of heat from the wine media that Hollywood stars do from the tabloids. I understand why he wants to answer only softball questions.
But in the paragraph immediately after detailing his physical ailments, Parker blows yet another broadside at people who don't share his tastes, saying,
"It’s funny that in the beer world, it seems like bigger and richer is what everyone wants, whereas in the wine world you have a group of hipster sommeliers who are basically advocating weird, undrinkable and deeply flawed wines."
