If I had constraints due to mixed company(adult idiots and children), I'd have joined the conversation and tried to steer it towards starting a petition on the WH website aimed at banning the sale of RPG's and rocket launchers in WalMart. I mean that is so irresponsible of them to do just to make a buck.
While we're at it, start a petition to force a ban on the sale of napalm at Sears and Tractor Supply Company.
