People on MW2

I just decided to post this hear because I'm REALLY annoyed right now.
Has there ever been a time when you wanted to kick a person from a game, ban his/her account, etc. because of something they did in Call of Duty or Halo or something?
I was in a game going for a nuke in MW2 invasion and was in my chopper gunner not paying attention to the score at all. I get them in a spawn trap and my chopper stays in that area (thank god) and I get a nuke. Again, not paying attention to the score, I shoot more people to rack up the kills. I check the score and there's 7000 points out of 7500. I see three guys in red boxes so I kill them, and then more spawn. The two that there are left to kill are in the house with a teammate nearby that I don't care about, just about getting out of the chopper and getting my nuke. I kill one of the two guys and then wait to get out of the chopper, really panicking that I won't make it.
Then, all of a sudden, I get out of my chopper, hit the nuke switch JUST as the game ends, and a game-winning killcam comes up. My mouth hits the floor and I immediately send a heated message to the person that got the last kill.
His response?
A laugh. "hahahaha"
I send him another message.
"hHAHAHAHAHA"
I know I was probably less mature than mr. laughing [insert many curse words here] and should've said something along the lines of "please be more considerate," but I couldn't get a nuke for ages and then all of a sudden I get one and one of my teammates kills the last guy for the last kill.
So yeah, has anyone had an experience with a person online, immature and annoying, that you just wanted to yell and scream and (cough) DESTROY MW2 (cough) for?

Today I had the delightful experience of getting my chopper gunner...again. On the new map, Trailer Park. I don't know how I did it, as the gametype was Hardcore Ricochet: Headquarters, but I did and as soon as I got into a spot and called in my chopper gunner it was destroyed.

But it was not destroyed by a stinger missile or a predator or a javelin. It was destroyed by a Harrier. Yes, a Harrier that I had previously called in was destroyed by a stinger and then an enemy one was called in. Two missiles from said Harrier later and I had no more chopper gunner to get my nuke.

(And to add injury to insult, I lost my 11+ killstreak by turning a corner I thought was safe because a teammate was there and getting shot in the back when I had only my secondary left to use as a weapon anyway.)

A 7 killstreak (that I, personally, got easily...but after that I was stressed because the spawns had changed so I couldn't get 11 easily) that someone else had acquired destroyed the 11 killstreak that I had achieved. How does that make sense? Why is that possible? I work my ass off in a gametype I just recently started playing on a map that I've only played a few times and is basically a shotgun/rushing/camping map with limited long-range views to get a chopper gunner and it is shot down by a Harrier that I couldn't fire at because the chopper wasn't even close enough to the map by the time I was out of the laptop.

Someone explain to Infinity Ward that 11 > 7, so that killstreak should have priority. Why add killstreak-ending missiles to an already two-sided blade? An airstrike and then a machine gun turret floating in the sky that also CONVENIENTLY has missiles to take out choppers? Thanks, Infinity Ward, you're the best.

[P.S. It's worse than a predator, which I would have been annoyed at very much anyway, because I just called it in and did not get any kills for it and the Harrier had been out for about 15-30 seconds.)
