I think that is hardly the point. We each decide how to carry for ourselves. There is no mandatory way to carry, good advise perhaps, but not mandatory.
As for me, I always carry my 1911 cocked and locked - no extra effort required. However, on the rare occasion that I carry a wheel gun (single or double action), I do not carry it with a cocked the hammer.
No one is talking about carrying "cocked & locked". We are talking about carrying a loaded weapon versus a unloaded weapon. Slight difference. Would you carry a revolver with 2 empty slots in the cylinder? That would be the equivalent of carrying a semi auto without one in the chamber. First empty slot would be so the revolver did not magically fire without the trigger being pulled and the second empty slot would be so it did not fire if the trigger was accidentally pulled.
People can do whatever they want. Is open carrying about making a statement or self defense? What if I carried without any ammo whatsoever? That is the safest way to carry a firearm. Zero chance of a negligent discharge. Am I actually open carrying then? Might as well get a blue gun. I worry more about people with firearms and zero training than I do BG's. More people get shot negligently/accidentally than they do with intention every year. Not having the confidence to carry a modern, properly maintained firearm with a round chambered, to me, signals a total lack of training and understanding of how a firearm operates.
I realize some people are timid and need to take baby steps in open carry. I try to encourage them to carry in the best way, percentage wise, to protect themselves and others as quickly as they become comfortable. If someone is hesitant to carry a loaded firearm how hesitant will they be to use it when their life or someone else depends on it?
Carry however you want but know if you ever took one of my defensive pistol classes I would quickly teach you how ineffective and dangerous empty chamber carry is. You would "die" in every defensive scenario drill we run.*
I use the term "you" in a general sense and it is not intended to single any one person or entity out.
