That Vice article and the pluralistic blog spam post don't understand what a Fudd is. A Fudd is a curmudgeonly, old fashioned gun owner who is judgmental about people owning modern firearms. They favor hunting and shotgun games over handguns and semiautomatic rifles. If they own handguns at all, think revolvers and 1911s instead of Glocks. Generally, Fudds tend to be very adamant about safe gun handling, often advocating for range rules that are overly restrictive like prohibiting aimed rapid fire. They're not the kind of people who point loaded handguns at their crotches to get a reaction out of people online.

The people who are pointing loaded guns at their crotches are mocking people who take the four rules of gun handling very seriously, including both Fudds and most "normal" gun owners. They're trolls that exist almost exclusively online. They don't make up anywhere near half of gun owners and they're unwelcome at pretty much any gun club or public range.
