The law is that of gravitation. Overwhelmingly in my experiences, the term "gravity" is used to explain the existence of this law whereas the invocation of the law is termed "gravitation". The dialogue of "gravity" is the dialogue of a theory because it is concerned with the interaction of a law on the universe. It has been conceptualised as this because it is deals with objects outside the mathematical realm.
I think that you are using "gravity" to describe both the laws and the theories behind it which is completely different to how I have been exposed to the term, where we seperate it. I should also point out I am not up with current discussions on this so my terms may be outdated but we use "gravity" pretty much solely to describe the nature of the force and "gravitation" to describe its existence which I thought I made clear.
You are using the terms differentely and while we do this we are going to have no common ground. If you are using "gravity" to cover everything then I fully agree with you it is not a theory or a law. That is not how I was using it, though, and that is not how I have been taught to use it.
I see the root of the problem now I think. You're calling something that is just a noun a theory and I don't know where you picked that up but its totally insane. The only time you can say a noun is a theory is if its a proper noun and the name of a specific theory. Gravity is, has been, and will always be just a noun. Saying gravity is a theory is like running up to someone and saying "Did you know arm is a theory". It makes absolutely no sense. You need more words because just gravity or just arm is too ambiguous. If you where to say "It is a theory that you can feel real pain from a severed arm" that would make sense. Likewise saying "It is a theory that gravity exists as a field" makes sense while "Gravity is a theory" sounds ridiculous. That and you do seem to have a rather odd sense of the terminology in general. The language of Physics is generally as precise as the mathematics so if you don't use it right you end up with nonsense.
