CSGV is lambasting it as serious. You know, I think if you put these folks in a dourness contest with a bunch of Puritans from early New England, the Puritans would have some pretty stiff competition.
And, oh, Guns and Ammo? The Zombie thing stopped being funny a while ago.
UPDATE: From the people who don’t want to ban your guns:
Yes, the Mossberg 500, one of the most common sporting pump-action shotguns in existence, and you have a CSGV loyalist who suggests the fact that these are sold is “Disgusting.” Yet they aren’t ever going to come for your guns. You can trust them on that. You’re paranoid for thinking that.
