Huh?
No one is "crying" about anything. If a discussion regarding gun rights occurring on a gun rights forum bothers you, I don't have an easy answer. As for any 'problem,' let's break it down. Is it a problem? Probably. I have never really heard a decent reason as to why, so I'll assume that the person that owns these shows thinks the only people that should have guns at the show are law enforcement and people with the exempt box checked. The rest of the public is too dangerous/stupid/negligent to be allowed to carry at their gun shows. This isn't an industry standard, as some allow carry, so what is special about these shows?
I don't presume to speak for the gun rights community, but it seems that most state and national groups aren't supportive of GFZs, so what recourse do we have? We could cry, but I agree that probably won't accomplish much. We could look for some legislative solution, but that may be difficult and possibly a waste of political capital. We could also let the organizer know that we won't attend the shows if they are going to have rule. If enough people did so, they may change it. After all, this isn't Starbucks or Target, where a relatively small number of customers cares about being able to carry a gun. I'd guess that gun show patrons, as a group, are more supportive of gun rights.
As for bothering me, I don't lose sleep over this issue, but it just puzzles me that people that say they care about gun rights would PAY someone that has demonstrated their lack of respect for them. It reminds me of an abuse victim that keeps going back to their abuser. It isn't like gun shows are the only place to find guns.
