Well, this is a complex issue... I mean RKBA when I say this, RKBA = The Right to Keep and Bear Arms. It's not necessary to post, or come to events to further the cause. All you need to do is be nice, kind, polite and carry everywhere you go (that it is legal of course). Furthermore, if you are not carrying, or not carrying visibly you can choose to only shop at pro-firearm establishments. So you see, activity is more then the eye can sometimes see.
