Ok, you didn't use the word irked. For whatever reason, though, you were compelled to disagree, and keep "going and going" with your disagreement, as long as I kept going with mine. Yet I'm the Energizer Bunny. Uh-huh. Oh, and I don't think arguing implies anger. If I let myself get angry (rather than mildly annoyed) everytime someone disagreed with me, or everytime someone decided to nitpick, I'd go insane.
Anyway, I will clarify that very little is actually wasted. At least I've learned a few things: you're convinced that, despite the fact that you replied as often as I, I'm the one who should've let it lay, who's going and going, etc. Right. I've also learned that, while I'm stubborn as hell, and know it, the latter might not be true with you.
And yes, you're the nitpicky one. Is it really that hard to believe, giving as how you've had a similar reputation for quite awhile here? Be it an insult, or a lighthearted jab (usually the second, thankfully), you're known for being precise and nitpicky.
