It's nothing to do with "liking the fact", and I never said that, or anything that can be extrapolated to that, so stop making shit up. IW are trying to engage the player on an emotional level, and that is what I like about this.
I don't understand how people can justify that it is fun to mow down civilians in GTA, but it's 'not cool' if the game makes you feel emotionally responsible for it. As Strider said, if anything, it's worse in games like GTA, where you get positive feedback from killing innocents, instead of negative like this scene in MW2.
It's already been said, but I'll say it again: you can skip the scene if you want to.
But I, for one, won't.
