This dude who is preaching right now is a little too animated for my taste but some people are into that.

Frequency and amount of absorbed power possibly. Most humans are somewhat grounded, even standing on earth in a pair of tennis shoes. An easy way to test this is to change a light switch and grab the hot. You will tingle. So the vaxxed, whether they are sitting in a metal chair, are sort of like an antenna as a result of the graphene oxide. Possibly, at a certain frequency, they begin to resonate and absorb power from the radio transmitter, and perhaps at some level of absorption, the physiological effects take place. Electrocution is different, you apply big power at the anode and connect to a suitable cathode and then you cook the organism. This radio method appears to effect the health of the human body operations rather than outright destruction in the case of electrocution.
This is a hunch only for more learned anons to opine on. My background is not electrobiology.
