Medical patients SUFFERED as a result of this film
For years, doctors felt like they could be the biggest *beep* that ever walked the earth. As long as they were "good at medicine", they could abuse patients and take advantage of nurses and other hospital staff with impunity. There were some compassionate souls in medicine, and by the 60's a more humanistic and compassionate view towards the patient begin to take hold among physicians. Then MASH came along.
This movie is a nonstop glorification of *beep* doctors. The protagonists do whatever pleases them at the moment, and everyone else be damned. It's not enough to treat women as sexual playthings; women have to be subjugated, enslaved, and passed around like a joint at Woodstock. It's not enough to disagree with someone elses political or religious views; those who disagree with you must be humiliated and destroyed. This all makes for a zany, anarchic, comedy entertainment (I admit I laughed as much as anyone when I saw it). The tragedy is, too many doctors in real-life saw their MASH counterparts as positive role models.
By the time I entered medical school in the mid-80's this film had taken hold of the physician culture. Residents and medical students on-call quarters were referred to as, "the swamp". Favorite teachers and house staff got nicknames like "Hawkeye", and "Radar". That in itself was harmless, but I also witnessed multiple incidents of patients being abused for the physician's own amusement.
When I was a third year medical student, I was told by an attending Internal Medicine physician to approach an attractive female patient and ask her to permit a nude photo of herself to, in the attending's words, "complete her medical record". When I asked the attending if this was true, he replied, "Hell no! I just want to see if she shaves her c()^t! The attending added that, if I refused to go along, he'd see to it that I'd never match in ANY postgraduate medical program (you can't practice unless you have at least 3 years of postgraduate training beyond medical school).
I could give you more examples of similar scenarios that I've witnessed in the last 25 years. In my opinion, few men are responsible for more human misery and mistreatment than Robert Altman and Ring Lardner Jr.
