That sounds like it comes from some Fundies Instructor trying to make crap up to make it seem like they know what they are talking about.
Yup, along other things, Chris and Danny are both Fundies instructors.
It actually happened to me once on my old 10W DR light. I haven't had a problem putting my Salvo switch on the "inside". Gloves, no gloves it works the same. Neither has a big ol' H on them like Mike's light tho.
