It does seem strange, with all the other issues that can be endlessly debated without getting into the snarkiness. Couple A practices safe, sane and consentual: Couple B practices Risk Aware Consentual Kink. They acknowledge they probably should not scene/play together and no one gets upset. Some get off on electrical, others don't -- and no one feels the need to get emotional and "defend" their rights to shock or not to shock.
This one issue, though, seems to arouse so much strong feeling in a loosely knit group that (as Shins pointed out) is normally tolerant and non-judgemental to an extreme.
Just sad, very sad.
Silke, i would love to hear your views.
