This is what I'm saying. He gets pissed at poor technique -- very Te.
The only reason he's not attempting to correct them (and this is why he gets so damned pissed) is because part of his technique is to not give the enemy any advantage, lest he... give them an advantage.
E_TJ is convinced they've got the method. Realigning those who don't adhere to it brings them comfort. Additionally when their method fails (his does due to 'stupidity'), especially more than once, they become furious.
