What I hear being said sometimes is that his love for Sakura is a bad thing. Naruto keeps his own feelings bottled up inside in order to make Sakura happy, and as Sai said it weighs heavily upon him. Sakura is inadvertently causing him a lot of pain, and when she finds out about it, she is guilt tripped into confessing to Naruto in an effort to rid him of his burden, even though she doesn't actually love him romantically. However, the way she goes by her confession is deceitful and almost patronizing.
Stating that she has fallen in love with him because he was there in place of Sasuke, and that unlike Sasuke he is a hero rather than a criminal, made her seem like the shallow type of person who picks out who she wants based on their status and popularity. This generated even more hate for Sakura amongst those who dislike her, and I think that's part of the reason people don't support Naruto's romantic endeavors- they just don't like Sakura.
And because they hate her they look for whatever excuse to put her down as a bad person. All that you described is interpretation based on negative prejudice.
At the end of the day all that Sakura has done so far has been out of care for Naruto, she thinks very fondly and highly of him. If she screws up is not because she's arrogant, it's because she had some bad ideas as to how to approach a situation. But the people that dislike her will obviously not see that and choose to portray her as some sort of bitter opportunist.
You say other people are biased and that they tend to interpret things in a way that supports their own views, but to be fair, aren't we doing the same thing here?
Bold: this is a good example of that. Regardless of whether or not Naruto actually does act neutrally towards her, you choose to interpret the scene in such a way that confirms your point of view.
It can't be an interpretation when the evidence is right there on paper. It's not up to interpretation whether Naruto made a fond face towards Hinata, it's a fact that can be viewed.
Now if I say something like "Naruto didn't feel anything romantic towards Hinata in 615", that right there is an interpretation. We can be sure that he doesn't show romantic love for Hinata (given his face), but he could be feeling it internally and not showing it. Although it's rather unlikely since he tends to show what he feels, but you never know.
I'm sure Harry's bond with Hermione was stronger, but in the end he still randomly fell in love with and married Ginny. Yes I brought that up again

Since you said you were just trolling I'll let this one slide.
Still, as said Harry never crushed on anyone at the beginning. And you know how in manga/anime romantic development uses way bigger emotions. It's all about destined loved ones, not casual dating. The differences between the east and the west in that regard is the same as Heaven and Earth. See what I did there.
