Nobody is arguing that Nate should use a Taser for masturbation, so that analogy is irrelevant. The point was that you described “electrocuted/tased/zapped” as though they have one inherent physiological nature, then jumped to thermal effects and being “fried to a crisp.” They don't. Different electrical exposures produce different effects depending on the current, voltage, duration, waveform, pathway, and device.
And saying that sufficiently severe electrical exposure can kill or cause thermal injury doesn't establish anything about the specific aversion procedure we were discussing. You're still substituting extreme electrical injury for the actual stimulus under discussion. The masturbation example doesn't establish anything about the therapy either.
And even your hypothetical about Turncoat doesn't imply he'd be “fried to a crisp.” Saying that a Taser can potentially cause serious injury or death is not the same as saying every exposure produces catastrophic thermal injury. You're repeatedly moving from “this electrical device can cause severe harm under some circumstances” to “this is inherently what happens when someone gets zapped,” which is simply not true. A specialized electrical-stimulation device for sexual use is not physiologically equivalent to a TASER, and neither is equivalent to prolonged high-energy electrical injury. You keep treating “electricity” as one uniform thing when the actual effects depend on the device and exposure conditions.
