Shimio
Does seem kinda crazy.
My reasoning would be, Sakura never deserved Naruto (not that she ever really had feelings for him) because of the way she always treated him. But a lot of people wanted to see Naruto "get the girl." At the same time, people were rooting for Hinata because she was the only one (though she never said anything -.-) to actually see Naruto for not just a bratty kid. There's a lot of indecision there.
Are people who are saying this also SasuSaku shippers? Because if so, then that is the biggest pile of hypocritical BS that I've ever heard. No matter how Sakura (and most of the others in his graduating class) USED to treat him, at least she never tried to kill him or put him under a genjutsu that had her ramming a fist through his chest. And despite Hinata's crush on him, she never did anything to stand up for him when they were kids. Even after Shippuden she did nothing significant until Pein nearly skewered her a**. Again people are crucifying Sakura for her past actions when characters like Sasuke, Neji and Gaara have done worse.
