I don't think Iverson should take himself out. If he was chosen as a reserve, then maybe he should consider it, but since it was the fans the voted for him he should show up.
With that said, what needs to be fixed is the voting itself and how it's done and how much power the fans have over the starters that are chosen. But I really can't hold against a player for being voted in... I hold the ignorant fans responsible... Unless the player is Chinese because we know that Chinese voting is absurd.
