So you met a bunch of people claiming to be "world champions"--happens quite a bit.
You CLAIM that is what he said--unless you have tape all we have is what you SAY he said with no-way to check.
Yes--ANYONE cam claim pretty much any rank they wish---there is no overall ruleing body for the martial arts. Which is EXACTLY why any martial artist with any degree of experience pays little attention to claims of rank.
I note that YOU ALSO claim to hold "a very high ranking"
"I could go into my beliefs and facts if anyone wishes to debate"
Actual "facts" would be nice.
