I guess I can see both sides of the argument here, being military, well retired military. When I see non-military personnel wearing military awards and decorations, it ticks me off. We had to work hard to earn those awards and even our ranks. I spent countless months deployed to some pretty austere locations which earned me some of those awards. My relationship with my kids suffered due to the many months I spent away year after year.
On the other hand, there are people who collect and display these awards so the stories of some of our heroes aren't lost. Seeing the family either threw the stuff away or sold it to an antique dealer or such.
So to keep it and display it with a story of what it is, the history of if, and how one would acquire it is fine. To wear it as a modern decoration or fashion accessory to me would be in poor taste, and maybe even border lining on disrespectful.
Again this is just my opinion, and we are ALL entitled to our opinions. Just one of the many things I served to preserve.
OK I'll get off my soap box and go back to my corner now.
