I don't believe that's what I said, and it's certainly not what I meant. Deception is wrong if it's meant for material gain; deception is not wrong if it's meant for entertainment - else magicians would have no audiences.
Many people enjoy being deceived when they know it's happening; they become challenged by attempting to uncover the deception - again, many people are fascinated by stage magic and sleight of hand. People do not enjoy being deceived, however, when there is a cost (or loss of potential benefit) - thus, people enjoy sleight of hand on stage, but not when it's used by a pickpocket.
Kacey, I believe you. I am certain your meaning is not what it appears to be. But, I don't know that the body double is quite the same as a magic trick.
I once paid for some tickets to see a revival of Jesus Christ Superstar. The billing included Irene Cara and Dennis DeYoung of Styx. When we were seated at the show (UMass Amherst), both Ms. Cara and Mr. DeYoung were no shows. I was quite upset, because I was led to believe I would be seeing these two actors on stage. I apprecaite the need for understudies, but when both headliners are no shows; something stinks.
In this instance, it is not that the headliner is a 'no show', but instead needs to attended to business offstage. This does not require a 'body double'; it gives the appearance that Ms. Cyrus can dance, in a place and time when people are not expecting to be fooled.
I have seen Stevie Nicks in concert a couple of times. Now there is a performer who has some costume changes (and an old coke habit) that needed to be attended too of-stage. Never did she use a body double. If she was off stage for a couple of minutes, the band vamped and everything was OK.
The deception is wrong. Is it a big deal? Of course not. But, I don't think it was a big deal that the essay was fiction either.
I think what had people up in arms, is that the fiction included a United States soldier dying. I think the essay raises some uncomfortable questions about soldiers dying; questions many of us would rather not face. I think those who were most outraged by the essay are cut from the same cloth as those who told me, when I vigorously opposed the invasion of Iraq, that I should leave the country or that I was a Nazi Sympathizer.
It appears that it is still taboo to question the military in any way.
P.S. Incidentally, I think the mother encouraging the girl to win at all costs is poor sportsmanship if you will. But, it is also the American way.
