I obviously don't know the poster either, but from what he's been writing, he appears to be offering at least some things that have been known--though not necessarily written as gospel--by many within Kajukenbo. By his posts, he seems to be offering (what LOOKS like) legitimate perspective based on either first-hand communication, first-hand knowledge, inference, or a combination of those things. Seems like a fair standard to apply.
As a Kajukenbo man--dating back to the late 1970's--and as someone who understands the occasional consequences of speaking freely, I understand to some degree why the poster chooses to remain anonymous.
Thanks, I think.
