That's true, but it's missing my point. The whole "drone war" is being cast as robots killing humans, mostly ignoring the fact that humans are making every decision about who to kill. This puts the focus of the debate on the technology instead of where it should be, which is on the people who have decided that it is ok to kill other people. So people protesting the program are demanding "Stop using drones!" when they should be demanding "Stop murdering people!"
I am pretty sure it's easier to dehumanize people when they are merely pixels on a screen.
