I've read Jaba's posts in another section of PPRUNE I frequent and he's definitely more restrained there in his attitude. I guess it is because there are guys there who know who he is in RL. His views do carry some weight there though, and sifting through his postings there definitely is something to be learned there if he could modify his attitude a bit. If he was a flight instructor with an attitude like that he'd find himself out of students in no time flat.
