simply put the one notion that the Naruto fandom in general and the NaruSaku fandom in particular needs to disabuse itself from is the notion that Sakura was lying about her feelings for Naruto.
let me make this absolutley and perfectly and finally clear.
She was not lying about her feelings for naruto.
the confession can be broken down into three basic elements.
1: Tell Naruto her feelings (or Naruto I said I love you)
2: Tell Naruto that he doesnt need to pursue Sasuke any more (Or so dont worry about the promise)
3: Tell Naruto she really does feel that way about him (Or only I know my feelings)
the only lie she told throughout the confession was during part 2. In essence the confession was supposed to be about the rookies decision to kill Sasuke. Sakura had insisted that she be the one to tell Naruto.
this is the source of the angry faces and shocked faces. everyone was wondering what the heck happened, for yamato and kakashi they could tell she was holding something back, and for Lee, Kiba and Sai they were suprrised because she was supposed to tell him about Sasuke, and instead confesses to loving naruto.
It was this ambiguity that Naruto caught onto and combiend with his image of team 7 as kids firmly entrenched in his head couldnt bring himself to believe her.
this snippet from Twin Enigmas story Five by Five very adroitley descrives what happens to Naruto when his picture of team 7 is shattered

The real Sakura tore into that memory out of nowhere, a surprise attack, and the memory hangs tattered in sun-faded ribbons. It shouldn't hurt, but it does because he loved it. He has accepted the memory Sakura as truth for so long that to lose her is like being blindsided and he almost resents the real thing for destroying that image, almost.
it is this shattering fo the mental image that throws him for the biggest loop. Also Sakura insistence that only she can understand her feelings. Her comment about women being ficke as the autumn Skies is a classic anime and eastern saying regarding how a woman can change her feelings.
As I've said before, Protecting someone requires you to by nature shut them out from what ever may hurt them, in this case the rookies decision would hurt Naruto and thus Sakura desired to protect him just as she did when the 4 tailed Kyuubi hurt her.
conversely confessing to someone by definition requires you to open up to someone at the risk that you might be rejected and thus hurt. this requires some courage to do as the risk can be big. Hinata only found the courage because at the time she thought she was going to die protecting naruto and thus had nothing left to lose.
Sakuras though took a hell of a lot more courage, because in her case she was not facing a life or death situation or a madman intent on killing her.
She was facing Naruto with witnesses nearby and the witnesses were her peers and friends and teachers. For a girl like Sakura this would be a big moment and she handled it well.
the only issue though was that you cannot simultaneously look left and right at the same time, and this was the root of Sakuras problem with the confession.
in conclusion for all the crap Sakura has taken for the confession the main argument is that shes lying to Naruto. Simply put this is not true. she only withheld one thing from Him and that is the rookies decision about Sasuke.
period end of statment.
