I'll preface that I don't like guns and I am not fond of gun discussions. That said, I don't agree with the idea that old time members should steer the forum to try and preserve the vibe. A good vibe is not preserved by not allowing what we don't like. That becomes a distorted, stifled vibe that has little in common with the original "good vibe". So to me, to continue having a good feeling in this forum, instead of preserving something by banning something, let things move through and continue contributing in positive ways. There may be changes, such is life, but closing doors to our little town because we like it the way it is, will turn it into a town with less to like. Let's have a little faith in this community. We can tackle uncomfortable subjects, even when they seem in greater numbers than usual.
"This isn't what we do around here..." is no way to address a clumsy visitor. Show them, instead.
