Harley, you asked, so here's my two cents:

I think, frankly, that your well founded points would have been better recieved at the other end without the accusation that his reply was "weak". He will most certainly bristle at that comment (wouldn't anyone?) and from that point onward his ears will be closed. If you alienate the man and the "AMA staff" then whatever gains you seek will be harder to attain.

He DID, after all, welcome your input as to whatever errors you found, offering to correct them.

I think that the phrase "you catch more flies with honey than with vinegar" applies here.

IMHO, Don.
