For the simple reason that putting yourself on web pages invites criticism , both positive and negative,By the way i looked at your dojo Webpage and viewed you video clips.No comment.
Hope you are well, Joe
Criticism period. There is no intrinsic requirement to be balanced in some way. For that matter no requirement for being constructive or fair. In this case the criticism is honest and to the point so I'd say that it is as good as can be expected.
As far as I am concerned this applies also to the clips posted by the club I train in althoug if memory serves I am not in those clips.
