Maybe because you are yet to validate your own background. Don't know Chris or his background, and yeah his posts can be bit hard to read for someone like me, but still, I do believe he asks valid questions. He appears to know his stuff, do you?
In context, I'd say it was a fair question. But also one that could be answered by reviewing the board. Chris has addressed elements of his training numerous times. You've pretty much complained about your training... and Chris answered the first time you asked. You... Yeah, not so prompt or directly answered.
So... credibility win on swords? Chris, hands down, I'd say.
