More important than where he got his green belt would be...where did he get his sense of propriety in the arts? Near as I can tell, he didn't log on with an actual fact-finding agenda. Rather, to stir the poop bucket. I say...ignore da bum. Mr. Bowles would be a perfectly fine person to train under. And if he was really serious about it, he would have found a way to get Mr. Bowles to communicate.
Seems more an agitant, than a serious seeker.
No doubt. He seems to be related to Gary Brewer given his manner. Still curious about his claims of training.
