Yes. All KNOWN operatives.
It is entirely possible that we have seen hundreds of characters who are operatives of Section 31 who have NOT advertised their membership.
Remember, I am saying that it is not likely that Section 31 members routinely advertise who they are. You can't claim I am wrong by saying that all the members we know of have advertised it, because that introduces a bias (namely, the fact that we are only looking at members who have advertised it).
And you can't appeal to the unknown to prove a point. You have no evidence, and you haven't said anything new for three posts.
It is not possible that we've seen hundreds of Section 31 Field Officers because we haven't. The rules of canon apply. If canon doesn't say red shirted ensign # 458921993 is Section 31, he isn't. Until canon changes its mind.
That's it. As of now, canon says Section 31 doesn't care about admitting it exists in casual conversation. Right now canon says that Section 31 relies on cover ups. If you ask for proof it exists you won't get any. There's nothing more.
In the future that might change but right now, that is the way it is. To show otherwise you can't appeal to what might have happened, you have to use what did happen. You need on screen evidence or a statement by production staff. Anything other than "might."
what I'd like to know is where are the other 30 sections?
surely there must be Sections 1-30 that have other responsibilities in Starfleet
DS9 establishes the name is officially "Section 31." Ent establishes that it comes from Article 14, Section 31 of the Starfleet Charter. Without knowing the content of Article 14, there's no knowing if sections 1 through 30 (or 32+ for that matter) can be used as basis for establishing anything. We do know that the name Section 31 does not automatically imply 30 other organizations.
what i think we're all trying to say is that nobody really knows for certain, and can we please just get back to the artwork? sincerely, etc.
Actually, I'm saying canon says "Section 31 won't kill you just because you know the name 'Section 31,' and can we please just get back to the art work?"
As far as I can see, the answer is "no." There's a fine line between keeping things on topic and trying to squash (relatively) free expression, and that's moderator territory. I'm not a mod so it isn't my place to play on that line.
Conversely, I've said all there is to say about the evidence as I know it so--absent newly presented evidence--I've nothing more to say on that subject.
