Wow. I'm certainly going to think twice before taking uke for either Bruce or Kevin after this. I honestly feel a little threatened.
I have no idea who can and can't hurt me and what they can and can't teach me by that. All I'm telling you is that my experience is that there are a lot better ways of getting me to move than hurting me. Is that stupid on my part? Probably. Am I trying to make some sort of macho point? Certainly not. Is it possible to move me with pain? Perhaps, but it isn't the best way to go about it, again, in my very limited experience.
