Not at all... I suppose we are after two different types of entertainment here. I'm interested in the performance; understanding of the music, inspiration, interpretation, execution. Most of my music consumption is audio-only so I couldn't care less about the physical appearance of the performer(s). "Confidence" to me relates to assertiveness in playing. If I can't hear it over a CD, then it likely doesn't matter to me. And if I'm watching a performance, I'm interested in the acting ability (in opera) more than someone's physical appearance. I don't care if it's Nikolaus Harnoncourt or Herbert von Karajan or Yuja Wang in terms of appearance. Their task is to communicate through music. Rhetorically, why should I judge them for anything other than that? I feel like some of these threads are getting weirder and weirder...
