I think just my .02$ worth is this.
The states/provinces have their own unique game regs which sets the stage for legal hunting methods & weapons in their own area. If its a "legal hunting method" in a perticular area, why as hunters try to judge other hunters when there are a ton of anti's out there that would love for us to start bickering amongst ourselves?
Heres a analogy. If I bowhunt traditionally & you bowhunt with a compound with carbon arrows are you being ethical? Its not in question b/c its a legal hunting method.
The other hand if you think ..............fishing for trout with explosives in BC on Lake Chilliwack is ok & BC hunting/fishing regs says its not legal, then its unethical, poaching & wrong.
All I'm trying to say is if its legal why give someone a hard time over the way someone else chooses to hunt or fish.
