I've watched american idol and survivor in the past and avoided feeling violated when I did so.
I consider such shows to be "mental Twinkies". They are sweet and yummy and fluffy, and totally devoid of anything nutritious, meaningful or relevant.
Its OK to enjoy a Twinkie every once in awhile, as long as you can be honest with yourself about what it is you are really consuming.
I have never watched idol or survivor....but I will confess to munching on a few mental Twinkies of my own such as "Moonlight", "Cold Case" and "Law&Order SVU".
