Just thinking about some of these "stolen valor" guys. Some of them are true scum-bags, but I think quite a few of them have a mental condition .....

that actually makes them believe they are soldiers or feel a desperate need to portray one. I kind of feel bad for the ones who are picked on and yelled at, when it's kind of obvious that they are in their own little world.
The ones who fake it for money or freebies are a different story though.
