While I imagine many viewers of Glee identify strongly with Kurt as a character, I think it may also be the degree to which Kurt crosses a line that may cause much of the passionate responses or reactions which you reference.
However, mileage varies as to how far over the line he really went, too.
For example, from my point of view, Kurt introduced his father to Carole to get closer to Finn. Kurt did not make the adults fall in love. He did not make them decide to move in together. They did that on their own. He is not an evil puppet master focusing his evil gay brainwashing rays on the adults to force them to do his bidding.
He sang Finn a love song. Awkward. I do not see that this was any worse than any of the other times that kids from Glee unleashed their inappropriate feelings on another Gleeker during the Assignment of the Week. Gives You Hell and Jesse's Girl in particular come to mind. Yes, I absolutely think that both of those were every inch as inappropriate. Every. Single. Inch. In fact, since Rachel was bitching Finn out in front of the entire Glee club and deliberately ignoring the assignment in the process, Gives You Hell was worse.
He grabbed $300 to redecorate their room "for Finn" in a way that he wanted Finn to want. That was selfish and delusional. It was also a subconscious way of expressing his feelings for Finn without actually making a pass at him. I do not think Kurt intended to make Finn uncomfortable. I don't think he actually expected to seduce Finn. I do think he just wanted to be near him. Remember, as far as Kurt knows, he's the only gay kid in Lima. He has no options at all. He can either be around the boy he has a crush on or be entirely alone. He chose the former.
I am not trying to suggest that Kurt's behavior was healthy. It wasn't. Most behavior in Glee is not healthy. It was delusional.
He wanted Finn. He flirted with Finn, somewhat subconsciously. That, and the disastrous attempt to decorate the room, was enough to make Finn uncomfortable. I do not blame Finn for losing his temper.
However, in places besides here I have heard his behavior described as sexual harrasment and predatory. I have heard references to gay rape. I never once heard Kurt actually say anything sexually oriented at Finn. He didn't make a pass at him. The nearest he's come to groping him was in the butt slap in "Push It" way back in episode two. Kurt's behavior was lonely and sad, but I just didn't see the constant aggressive, leering harassment that others see. He's got nothing on Jacob harassing Rachel.
Actually, I think the comparison to Rachel scrubbing Terri's floor to get to Will is quite on the mark.
I never thought Kurt and Finn would ever stay mad anyway, but did Kurt grow at all from his experience?
Now, that's a fair question. I agree with the "fanwankers" that the glance during Journey was intended to indicate that Kurt accepted the romance of Finn and Rachel. I agree that Kurt accepts that Finn is straight. However, I also agree that the writers did not really finish the story completely. They had a big problem with that this year. They didn't properly finish Shelby or Jesse's stories, either, and Kurt's story got further than theirs did. From what I understand, Theatricality was supposed to come after Funk, but they switched them around because Theatricality was a much stronger episode and they wanted to run it during sweeps. To that end, a LOT of material got switched around or deleted entirely. Burt and Carole were originally written into the finale, and that got left out as well.
Maybe they should have spent more time tying up these loose ends and less time making Will seduce Sue.
As for Kurt - without spoiling anything specifically, we already know he's got a big storyline next season, and it's not about Finn. We will just have to see what he's learned.
