Maybe for you, but not for all gun owners. And my point is that it's okay - if the guns are legal and the owner is excited about getting a new gun there isn't an issue. So if you know people who post pictures of their new guns with funny captions how do you know the person is about to snap?
I've known my nephew his entire life and when he posts a picture of a new gun I don't freak out or worry that he's going to go shoot up a church.
You wouldn't be able to get pink guns if people didn't want to show them off the same way they show off cars or bikes or guitars.
