zappers vs blood electrocuters

oh as a 63 yr old newcomer here, with a lifetime of various manifestations of inflammation and poor immunity, osteoarthritis since late teens, multiple cervical spinal fusions and an upcoming hip replacement, I am saddened that human communication is corrupted by misinformation or simply conflicting goals, what with the Parazapper and Jaguar57 accusations agnst one another. Is it necessary to call someone a liar as if their intention is to mislead and harm people? Can it just be that you have different intentions or base your research on different assumptions. If your arguments and differences are simply a matter of wanting to sell your own product, why can't you both be real with one another and the public - like me. I know that everything in science, as in History and sadly politics, is INTERPRETATION. This mudslinging doesn't leave me with full and practical knowledge - just eenie meenie minee mo.
