I can't believe that this thread is still active (or that I'm still reading it
).
All of the talk about concealed is concealed and you're a pussy if you don't carry, ditch your friends, etc. is pretty much off base. Either you respect the homeowners wishes, or you don't. Everyone has the right to run their house the way that they like. If respecting that puts your panties in a twist, don't go.
And all of the internet commandos talking about making a scene, or going out of their way to make a point. I'm glad your not my friend. I have friends and acquaintances with a wide range of beliefs and customs. I respect them because they are my friends, not because I necessarily agree with them.
Hell, if it bothers you that much. Invite them to your next cookout and make sure the invitation says 'gun required'.
