My Eenglish nawt two good butt... it appears to me that the word 'regulated' refers solely to the Militia.

You have it exactly right. It is the militia which is to be regulated, not guns. And "regulated" at the time of the adoption of the 2nd Amendment meant organized, trained, and disciplined. It didn't mean restricted or limited.

Or rights or the people.

Unless we're discussing the militia the definition of 'regulated,' then or now, is irrelevant. The only reference to the 'right of the people' is "shall not be infringed."
