What I've noticed is... that the farther someone gets into a certain specialty the more they tend to think their way is the best and anybody else is a slob.
The high-tech rifle guys who reload thier own bullets, shoot tiny groups at 500yards and know exactly where to aim on a deer walking 10mph with a 15mph crosswind @ 263 yards are a lot like the selfbow trad guys. (even tho' both groups are also worlds apart) They are both ultra-devoted to their specialty and think anybody who does it different has a lack of discipline and/or ethics.
It's not just a bowhunter thing... tho' bowhunters are notoriously cliquey and weird about equipment.
People just need to feel 'special'.
BTW, if you don't hunt with a 9 year old, round wheel, XI Demon compound... bowfish with a Oneida T-III, slug-hunt with iron-sighted 870, rifle hunt with a Rem 7400 (must be a 30-06) or trap 'coons with 160 bodygrippers... then surely you are an unethical, out-of-control glue sniffer.
.... because my way is the only true way.
