Hmmmm, maybe, but even though this is not really part of the main story, maybe Kakashi would have one of those realizations on where his life is going and whatnot, that maybe he does want to start a family?
heh- that'd be pretty cool- but it just doesn't seem like him to me- maybe its because Kakashi has taken a laid back kind of stance everyday- i feel like he's a creature of that kind of habit. He's had time to move on from rin and obito- to try to start a new life- but we haven't ever seen him try. who knows- maybe naruto can talk-no-jutsue him about it and he'll give some thought to the matter

I will say though, that Obito's feelings for Rin were definitely portrayed in a very selfless manner. However,
I'm not sure if they would've ended up together because of that. I mean, right after Kakashi tells Rin that Obito loved her, she attempts to confess her own feelings to Kakashi. I don't know, that just seemed low to me. Maybe it's just the heat of the moment, or just the fact that Rin didn't have a lot of time to dwell on Obito's feelings for her, but I'd think finding out that her comrade, who just sacrificed his life for her, was actually in love with her would somewhat undermine Rin's feelings for Kakashi. Though I suppose Rin was such a minor character, maybe it's just hard for me to empathize with her in that scenario.
But again, I don't think the character parallel was meant to be foreshadowing. Even if I'm wrong about that, though, we still have other parallels helping out our pairing in Mina/Kushi and Jira/Tsu.

It's good for NS as long as Kishi intends Naruto to be the nice guy that gets the girl he loves. That, I think, is the main point being made by having such a parallel.
It would make the most sense to show these very similar past romantic interests that never came to be in comparison to Naruto who struggles just as much, but will be the one to change the pattern. So yeah, I think it's good for NS. As far as Rin being cold, she might have expected that they were all going to die. But who knows. Kishi obviously thought it was a fine moment to confess XD;; so he put it in there. *shrugs*
You can have a hug too XDD

This is a TL:DR kinda thing- skip it if you don't fancy rumination
hnn- maybe its just me- but about your points by you guys- i get a feeling this might be the reason that so many people don't like NS (asides from the shipping angle). On one side there are the fans who feel NS occuring would make Sakura into a trophy wife. On the other side- perhaps there are people who feel like its not fair that naruto has to struggle to earn Sakura's affections. Perhaps what they see in NS is how doomed and tragic obito/rin is. There's something i remeber in that a speaker on psychology at High school once said, For people, every one negative comment directed at them, needs 10 other positive comments about them to balance out the emotional stress. Do you guys think that all those people who hate NS- remeber tragedies like how Jir/Tsu and Rin/obito ended, much more clearly than they see the happiness naruto and Sakura find in everyday things with each other?
maybe i'm just thinking too deeply- but perhaps this is the mistake kishi made in trying to promote NS- is it because of the similar characters with similar romantic situations in the past had met untimely ends? that some readers can only remeber that v.s. the themes and ideals of the story- that Naruto's end with Sakura would be different?
Because sometimes i get the feeling that reading the themes and ideas- Oh naruto is amazing- he can do anything- he'll defy the problems that plague the past! Themes like these are all over the place in shonen manga- to the point that the theme itself can get on readers nerves.
Its kinda like your parents lecturing you about why you shouldn't do drugs- i mean yes its important but to hear the same message again and again from school and classmates- till you just shut off your brain when someone lectures about it again.
Maybe thats why a lot of naruto fans' just don't have any positive feelings towards NS- they've shut off their brains to the message the author is trying to tell you- and sticking instead to the one that they got initially- believing it as more correct.
i don't know- bigotry is a strange beast- it just seems to rear its head a lot when it comes to shipping.
Unless Kishi decides to make Hanare canon, well, that's another story.
who's Hanare? sorry i don't know this couple >.<
sorry in advance if i'm going off topic
