Tornadium - That's a very good, well-reasoned reply.
In the interest of full disclosure, I'm going to say that at this time I'm a KyonYuki shipper. So... I'm not entirely unbiased here. Like many other KyonYuki shippers, though, I'll admit that my preference goes against the current for this anime franchise, particularly its fandom. I don't expect to "win" this any more than I expected my Ryoga/Akane preference in the Ranma 1/2 anime to emerge victorious.
All I'll say is that a lot of the Kyon/Haruhi relationship moments strike me as possibly being close platonic friendship moments. They tend to be viewed through a romantic lens, but... friendship alone can explain most of them, I think. Just my opinion.
Anyway... I'm going to let the shipping debate go for now, because this really isn't the thread for it, lol.
