Putting aside all the matters this relates to for a second, posting a photo of yourself in a messy house with a gun in the UK, show a lack of awareness at best
I know a lot of people who shoot - literally dozens, I should think - and for some of them it's a big part of their lives (gamekeepers, for example).
I'm FB friends with a fair chunk of them, and they would never pose on FB or any other SM like that with a gun in their living room, including the Americans. You might, tops, get a shot of someone with shogun broken over their arm posing with their dog at the end of a morning's wildfowling or whatever.
Most gun owners are very discreet about it. Broadcasting the fact that you own so much as an aged shotgun is just not done.
So yeah, this sort of behaviour is totally inappropriate.
