I never implied you did, they are merely one of the two major major groups of programmers I see consistently deriding C based infrastructure that presumably enables their paychecks to a large extent.
I'm not defending C, I'm merely sneering at its noisy detractors who spend more time complaining about it than supplanting it.
As for managed code, it's being used with huge success in a lot of places (not in OS-es or drivers, yes) but that's quite the huge topic by itself.
