The strawman, red herrings, glittering generalities...those ad hominems do get thrown around a lot, and it really does cloud the discussion.
And to be as fair as possible, there aren't too many people on the planet who 100% fit a stereotype. But stereotypes do exist for a reason, and people get called out on it when they start exhibiting too much of it.
In one of your first posts about this here, you asked for a definition of a Fudd, and for examples of JVB behaving in a Fuddly manner (my words, not yours). The info I shared in defining a Fudd, I believe, to be a pretty fair explanation of their mindset, behavior, and what most people tend to mean when using that term, at present. I also attempted to show that being a Fudd isn't an all-or-nothing thing, but a bit of a spectrum. But it is a very real thing - and you see different flavors of it in different hobbies, like different generations of car guys, music enthusiasts, etc (there does seem to be a generational component to it)
As to JVB, he's used a number of ad hominems of his own on the small cartridge issue, mostly various forms of appeals to authority and glittering generalities, to act like a Fudd. Types of "everybody knows", "it's always been done", the like. Making thinly veiled references to Form and others on here as "self-styled experts", as though he is any more of one for being a gun commentator. But he also somewhat advocates for the "Taylor Knockout Formula" and frontal diameter as a proxy of "wallop" - stuff like that, of very questionable scientific validity, that would in theory mean you can't kill well with an arrow. But the bottom line is he's dismissing a huge amount of data and accumulated personal experiences and annectodal evidence here that, all added up, can't be dismissed. And that's the core of his Fuddery to me - dismissal of evidence and new ways of thinking because he knows better.
That said, I personally think most hunters have varying degrees of Fuddery to them, but they tend to be issue-specific. Totally dressed up like a Kuiu Kenny instead of flannel and jeans, and shooting a 30-06, but one with match bullets out of a carbon-fibered sub-MOA gun. That, or buying into a couple of bits of Fudd lore, while not being much of a Fudd (this happened recently to me personally, regarding shooting non-Garand 30-06 ammo in a Garand. TLDR, it's fine, the data's there, but Fudd lore means most people just know better, repeat it, and dismiss claims of guys who've done it as dangerous or just lucky).
