Thanks for asking:
1st explanation: In college I was the only Christian in a dorm filled with some of the worst alcoholics in the world. (I do drink, in moderation...but these guys.......sheesh) I found one of them passed out on the bathroom floor in his own puddle of puke. I cleaned him up as best I could and carried him to his room and notified his room mate to come back to the dorms to watch over him and make sure he was ok.... I feared alcohol poisoning. This got into the campus paper and my new nickname was "Saint John". I thought that Sainthood was a little out of proportion... but when the reporter asked me why I did it... I told them that "I am my brother's keeper". So people started calling me "Brother John". It stuck.
2nd explanation: I am a Christian. In church we often refer to each other as "brother" or "sister". I believe that we all descended from Adam and Eve... therefore on some level I AM your brother, and you are mine. I take that to heart.
3rd explanation: I am a 32nd Degree Master Mason. ((If you don't know much about freemasonry... look it up on your favorite search engine)) In masonic lodge we refer to each other as "brother". We also truly espouse the sentiment and action of the "Brotherhood of all mankind".
4th explanation: I feel that the Kenpo community overall needs to be a little bit more aware of our common roots.... despite our differences. Thus I'd like to be yall's brother.
5th explanation: When I began writing on these forums (and some others) a few years back I needed a cool moniker... thus: Brother John....
Hope this helps.
I've had people who disagreed with me (go figure) and have taken offense at me saying I was their brother.... but I always say...NO matter what, If you and I never see eye to eye on anything and can't stand to talk to each other....
I AM your BROTHER... as in, I am no better nor worse than you are.
Later guys
Your Brother
John
