I must say the attitude of this thread is annoying me. The main thrust of what people are advocating here is (figuratively) shooting the messenger.
Consider what a physician has to know to do the job: a ton of anatomy and physiology, pharmacology, microbiology, psychology, sociology (and many other -ologies) and how they all fit together to make this quirky thing we call a 'human being' tick. Despite the 'Minor Deity' complex that some physicians get, no one can know it all. So how do docs deal with it? They take 'expert advise' from 'expert sources', such as the American Academy of Pediatrics, the American College of Obstetrics and Gynecology, the American Academy of Family Physicians, and a myriad of other sources - especially when dealing with things like patient handouts (much cheaper to buy ready made, and they carry the weight of the Big Organization). How much each physician buys into the material depends on each individual physician, and they may emphasize different areas. If you really want to get materials changed write to the organizations putting out the anti-gun crap. These doc organizations are very political and can be swayed by public opinion. Write a letter! Or, educate your doc and have them write a letter.
Giving your doc a document to sign on the liability of the advice they're handing out on a specific subject is downright insulting and may well get you fired from that practice. Having a civil discussion of 'hey doc, I don't agree with the info you have here. I happen to know a lot about this subject, let me show you some other sources' will go a lot farther in getting your point across. Otherwise you may well be selling them that gun owners are jerks. Education, not confrontation. Golden rule - how would you prefer to be treated?
