kraigwy, I think Old Grump's issue was not the combination of flag and rifle, it was that the flag appeared to be laid out on a platform of some sort, with the rifle resting on it.
I think Grump would have been fine with it, if the flag had been hung, and the rifle on a stand or similar in front of the flag.
When I first saw the photo, I liked the composition and effect. When I read Old Grump's criticism, I understood what (I think) he meant, and realized he had a point.
Meanwhile, I'm happy with straight-shooter's recent post, where he recognized and recanted his harsh tone. And, like I said, I like the composition and the rifle. And I don't think he realized that anybody might take issue, nor that he meant to offend in any way.
