I think this calls for my response.
Suppose some guy comes up doing some really crazy looking stuff, wearing a T-shirt that blasphemes Islam, for instance, wearing a Pirate hat, and tells everyone he's doing Zen Shin Kan Aikido.
And suppose further that he says he learned everything--even his blaspheming Islam--from Graham Christian?
Will you then say "It's all good"?
Would you really? Would you not even post somewhere that "This guy is NOT my student and I didn't teach him any of that?"
I can't believe you would allow that kind of insanity to parade as something you endorse. And if you don't speak against it, you tacitly endorse everything he says.
Would you really just remain silent?
