Why is the boonie cap so demonized in the army?

I don't understand the issue. All the other services limits the wearing of the hat. THE MARINES: The MCCUU garrison cap will be worn in garrison. The MCCUU field (boonie) cap may be worn during field-type exercises and operations onlyThe MCCUU garrison cap will be worn in garrison. The MCCUU field (boonie) cap may be worn during field-type exercises and operations only.
THE AIR FORCE: Deployed Airmen, or Airmen as authorized by MAJCOM, may wear the OCP boonie (campaign/floppy) hat with the Desert Flight Duty Uniform when theater conditions dictate.

Because it is associated with Vietnam. I served during the Vietnam war and I'm still hated for my service.I have old bags my age tell me all the time "My father served during Vietnam, I hate my father and I hate you" ! Girls back then wouldn't talk to us or dance with us. They would hide in doorways and when we walked by would hit us in our backs and runoff shouting bad name to us. So I never married,why marry someone who hated me for my service.

It is a subject I know nothing about and was not aware that the boonie cap was demonized.

I don't know. When I was an enlisted soldier I wore a boonie cap whenever I could. I thought it was good headgear.

SFC said it best, comes down to CSM’s preference. I convinced mine that it provided better protection from sun exposure AND while training troops on camouflage techniques it gave a better broken profile making it harder for the enemy to identify the Soldiers. He smiled and said that was a great, well thought out, bull shit answer so yes, he would approve everyone wearing the boonie

It brings joy to the masses, what better reason to hate it?

The 20th EN BDE SGM in Iraq circa 2008 hated them. I'm sure they'll be a lot of skin cancer VA claims in the next few years. Now in some other deployments the boonie cap can be pain to keep on in the wind. In about 84 or 85 I did have a SGT going to Honduras get one and he put wire in the brim and looked like he was in a Zorro movie to that extent I can understand the SGMs displeasure. I still use my accumulated boonie hats for keeping the sun off my face and neck in the retired life for yard work.

The demonization of the boonie cap stems from ignorance and inflexibility.

A LITTLE HISTORY, THE US ARMY KNEW IT WAS GOING TI FIGHT IN THE PHILLILINES AND DID NOT HAVE A SUITABLE HAT FOR THE TROOPS FOR A JUNGLE ENVIROMENT, SO THEY DEVELOPED ONE AND ADOPTED IT AS THE 1904 FIELD HAT W/A 3" BRIM AND W/A "V" VALLEY TOP, NOT TO BE MIXED WITH THE DI STYLE HAT. IN 1912+_ THE USMC WAS PLANNING THE MEXICAN CAMPAIGN AND REALIZED IT'S CURRENT CAP WAS NOT SUITABLE FOR THE MARCH FROM PANAMA TO VERA CRUZ, MEXICO, AND NOT HAVING THE TIME TO DEVELOP, TEST, BID OUT FOR A NEW HAT, WENT TO THE ARMY QUARTERMASTER AND PUCHASED A LARGE QUANTITY OF THE 1904 ARMY HATS, PUT A USMC PIN ON THE FRONT AND WENT TO WAR. MY GRANDFATHER WAS ONE OF THOSE MARINES.
I HAVE PICTURE POSTCARDS FROM THAT TIME AND OTHER MISC TIBBITS FROM MY GF'S SERVICE 1912-1916.

Wear the boonie if it's just right fuk em
