JP has some skill. He's a good guy. I've sparred him and watched him spar his ass off in a moderate contact tournament, fighting 6 or 7 fights (max 3, 2 min rounds as usual) but in something like just a 2 hour span of time. Irrelevent of the source, he's no slouch.
That being said, I despise SD because of the lie. I myself was duped for 13 years (not by SD) ...but gained some skill irrelevent of the source. However, because of the lie, I walked away and burned that bridge completely down. I would say I was humiliated the first time I showed up at the GLKFT, but the mantis folks there were very nice about telling me what I was doing wasn't mantis. If it's made up; say so and the proof will be in the pudding. Lying to stoke and/or protect your own ego is total bullsh!t, especially when you are taking money from someone.
Ironically, one of my last, closest students just started training SD. I think he's an idiot because the SD school here is not the best option for training available. All other schools are about the same distance and about the same price. And, when I shut down, I turned him to the mma coach I'd trained with some, this guy is not very well known but he was Spencer Fisher's first coach. In his idiocy, he 'don't like grappling' and doesn't want to train karate...but want's to train 'something'. I didn't even say anything in response, if he didn't get it after training with me for 4 years, it's a lost cause.
My point with the last paragraph is that, as said, it's hard not to blame the duped too because the liers wouldn't get away with it if there weren't a large percentage of people wanting to believe the lie.
"George never did wake up. And, even all that talking didn't make death any easier...at least not for us. Maybe, in the end, all you can really hope for is that your last thought is a nice one...even if it's just about the taste of a nice cold beer."
"If you find the right balance between desperation and fear you can make people believe anything"
"Is enlightenment even possible? Or, did I drive by it like a missed exit?"
It's simpler than you think.
I could be completely wrong"
