Does it change things if the store has a sign but their true stance is that they don't care as long as your gun stays holstered?
To me it does. My opinion is that a persons moral standing is more important than any sign. If they don't mind loaded firearms being in the store, then they shouldn't have a sign telling people to unload. As long as you practice what you believe in and stand firmly behind your belief's, I respect you. Even if they aren't the same as mine. But being a complete hypocrite is the same as giving your man card away.
It's the same thing as someone asking you to leave the restaurant or take your gun to your car. Most people choose to leave because they feel it is their right to be armed. However those same people will gladly unload before entering a gun shop. Also, are the employees at these shops allowed to carry loaded weapons? That's another subject of hypocrisy by itself if they are.
It's really not that big of a deal. I just couldn't believe how many people on this board feel it's okay for a gun shop to tell them to 'take their gun to their car or leave' (so to speak) but not a restaurant or other establishment.
