To some extent that’s all true but if “the individual using it” is wounding animals then it’s everyone’s problem. I already confessed that archery was unethical for me so I don’t do it. Yes, we label methods we don’t use as unethical because we don’t use them because they are unethical.It's not the equipment choice, it's the individual using it.
If a person is simply not profficient enough or cannot exercise self control when hunting with their chosen equipment and attempts shots beyond their skill/practice, it's the hunter that is being unetical.
The same rationale can be appied to a hunter who hunts with primative equipment or the hunters who uses ultra modern centerfire rifles and all the accompanying kit to shoot long range ........and every hunting method in between.
I have my personal views on some hunting methods that I choose to keep to myself as it's a very slippery slope when we (hunters) start label a particular method (usually the method we ourselves don't do) as unethical.
