No, it doesn't. I said it's grammatically incorrect, not orthographically incorrect. (It's arguably correct orthographically based on the incorrect grammar.)

> [Noun], being [clause], [grammatically correct sentence]

is objectively incorrect English grammar.

Eliding the "being" appositive, you're left with

> [Noun], [sentence].

Unless you're talking to the noun (as in "Hey, you, the well regulated militia! Did you know that the right to keep and bear arms . . . "), it's not grammatically correct.
