Can you please direct your discussion to the topic rather than to the people behind the topic? Let's stay away from making things personal here.
Dear MR Akiyama,
I suggest you address this issue [personalising ]to Mr Harden.[who passed judgement on Chiba Sensei]He is the one in this particular instance who instigated the subsequent response from Tony.Of course if you are making a general comment fine by me.
It just seems to me to be coincidental that you respond after Tony asks a valid question from D.H. Tony may well be seen as an irritant but in this instance I believe he has a point.You of course are the Moderator , so whether I agree with you or not , you call the shots. Cheers, Joe.
