Drones and missiles

Why is anyone upset about Drone missile strikes as opposed to aircraft missile strikes?  They are both fired by pilots with the exception that one pilot is riding along while the other may be thousands of miles away.  Is it a question of sportsmanship that an enemy can shoot back and kill one but not the other?  The whole concept of rules of war is insanity based i.e. you are allowed to load your gun with lead or steel jacketed bullets but not with exploding bullets,  Both can kill.  And dead is dead from either one as if there are degrees of being killed and dead.  It makes no sense whatever.  Is this whole controversy an attempt to make news where no news is?
