So what would back up the claim or facts from millions who understand how they work, plus those who design and build them, are they wrong?
Perhaps Graham's Hierarchy of Disagreement will be of some use to you.
Currently, you alternate between "responding to tone" and "contradiction", introducing an occasional
straw man along the way. For people to start taking you seriously, you'd have to bump it up to "counterargument" or "refuation".
Very importantly, saying "millions of people believe/know it" is not a valid argument in this case. It's a common logical fallacy known as
argumentum ad populum. The popularity of an idea does not say anything about its truth value.
