Its the way they fest receipted the dynamic, first impression, another if they saw the manga or anime first and generally most first saw the anime. Naruto was released in the U.S. in manga form back in 2003 but it was largely unknown until people first saw the anime in 2005.
Also its due to what the anime had shown different than the manga, otherwise the fillers too, you get stuff like sakura hitting naruto in the anime as a common generic shounen type deal of idiot hero tsundere heroine who whacks him when he does stupid stuff. But this common gag apparently is somehow an issue to most NH and SS fans.
Otherwise also the fact of well people will argue and make stuff as they go if the story isn't in their favor since its run the way it has.
My first impression before I really knew most of the story was NH (at the time, my reasoning was "well, she likes him, and Sakura doesn't seem interested..."), but it probably helped that I didn't really hardcore ship anything other than MK for a good while. And, I guess I really do prefer pairings who actually interact in canon, too.
Anyway, to me, it seems pretty obvious the manga is going to end with NS being canon...but others are so set on their opinions, and I'm (usually) not one to pop bubbles, heh 
And then there's the fact I think it's wise to have an open mind and admit that there's a chance I might be mistaken somehow.

. They make Naruto look like a complete fool and exaggerate Sakura's Tsundere-ness.
