Which brings us to another point,
Does the prevalence of "Zombie" stuff, grips, ammo, targets etc reflect on gun owners poorly? Maybe presenting some as not taking firearms seriously? Does it give the impression that some gun owners consider firearms a toy?
My opinion is that it can though I will concede that I know no one, family, friends, club members or co-workers, who buy this stuff so I can't say that I've seen unsafe behavior related to it. I also know that I "have no sense of humor that I'm aware of" so it could be just me.
