Someone on a review said that Sakura treats him like that, because he had the kyuubi in him and then the person said "Naruto's human just because he has the kyuubi in him does not give her the right to hit him." Sakura didn't know he had the kyuubi, but that was the persons reason.
My only answer is this: Shove me. Prove it. Back up that statement.
Show me one single scene where it was said Sakura knew he was the kyuubi's container before the timeskip, and she hit it because that. Show me one canon scene where you claim it happens. Link me to the manga page where it allegedly happened.
SHOW ME.
Sakura herself stated why she disliked Naruto in her first appearance: he was an annoying kid liked seeing her struggling, didn't understand her at all and was always interfiring with her love life (she was wrong about he liking to see her struggling and not understand her, but I wouldn't say she was wrong about the rest). Naruto being the Nine-Tailed fox never entered in the conversation.
And she has never hit it because he got the kyuubi within. Let's recall when Sakura has hit Naruto and why:
- When Naruto accidentally kissed Sasuke. He was not only interfiring with her love life and bothering her crush but also he stole the kiss she thought should have been hers.
- When Konohamaru asked if she was her girlfriend and Naruto said "Yes" to HER face. Any girl would be enraged cause that presumption.
- When Naruto -loudly- declared he was going to pee in front of Sakura and Sasuke. She hit him screaming you don't do that in front of a girl (then again, she thought she would like Sasuke did just that, but IMO that statement was only making the situation more comedic).
- When Naruto shouted Konohamaru that erotic jutsu was too lousy and he would show to him his improved erotic jutsu. She was blushing, thinking he had matured, and then he proves he is still a pervert brat, letting her down (by the way, if you have realized, we have gone around two hundred chapters between hitting scenes).
- When Naruto called her accidentally a cow with monster strength after battling Orochimaru. That isn't anything a girl would appreciate.
- When Naruto returned to the village. She walloped him on the head for being reckless and nearly getting himself killed.
That is all hitting scenes in the whole series I recall right now. How you can see, they barely are six. I don't recall all of them (and I don't count the time where she accidentally slapped Naruto after Sai called her an "old hag" because she was trying hitting SAI, and she accidentally hit Naruto when he got in the way), but I highly doubt the total amount reaches one dozen (it should destroy the "She is always hitting him! She is more violent than any tsundere!" argument, but I know character bashers don't care for pesky things such like objective facts). All of them happened after Naruto has done something stupid and has gotten Sakura angry or worried. And all of them are played out like comedy (except by the last time time, where she hit him because he had frightened her).
She never hit him because he was the Kyuubi. Period.
