"That's not you observing electricity, that's just seeing something electricity does heathen."
Those guys probably.
Their argument seems to be that since you can't actually see it, as in you can't pump electricity into a clear pipe and see flowing through the pipe like water. That "science" must just be lying to you.
What they're saying best I can decipher is that seeing that bolt of lightning or that arc from a wire isn't you setting the "electricity" itself. It's you seeing something that it's doing. Like the arc is a shadow puppet and "electricity" as they define it is the hand casting the shadow.
What they essentially want is for you to be able to take a picture of a lightning bolt and zoom in to see the individual electrons moving through the air. Fundamentally entirely misunderstanding how science says electricity works.
