You should judge an argument on the strength of its logic, not the resume of the one who said it. You'll have to judge for yourself if my opinions have any value.
The point is this. If someone who has 3 months training in an art, how can they honestly know the ins and outs of the system? This is all compared to someone that has 20yrs in a system. I have over 20yrs put into Kenpo. IMHO, I feel that I'm much more qualified to comment on that art than say someone with 1 month.
