Why do you want to take that time in the field away from anyone over an equipment choice. Afterall the bow is just the weapon it's really about the hunt so why do care what kind of equipment they are using?
Silent, I don't want to take anything away from anyone. Right now, in 47 states, the only choice is a bow for archery season. I wouldn't argue to remove crossbow hunters from archery season if the states I hunt suddenly changed their minds and made it legal for them.
It is true that slob hunters exist and hunt each fall, just as there are guys who are poor shots with bows. What I don't advocate for is if someone is not a decent shot with a bow allowing them to pick up another weapon to hunt with. I would feel the same exact way if someone came up to me and said that they don't shoot muzzleloaders well, the whole measuring powder correctly, the tamping and all that is hard to get right each time, making them erratic shots ... so shouldn't we just let them use rifles and shotguns??? I'd say HELL NO to them to.
