I'm sure that's exactly why you're showing no sources.
Therefore, if you dispute that each packet of internet data traffic must be read by every piece of hardware which it passes through (i.e., public), then you are welcome to debate that point in any manner in which you seem fit.
There's a difference between a piece of hardware and a person. No doubt, though, 200 posts from now you'll be saying I deny that packets of information are read by the hardware they go through.
Why leave such ambiguities to chance? Why not just state, unequivocably, that you either think that all internet packets are read by all machines (regardless of who owns each machine) that they cross, or not?
Is it really so difficult for you to take a black or white, firm stand on a single point?
