With respect, you are cherry picking and generalizing to suit your fancy.
Lumping gun hunters together into a "more unethical than bowhunters" category, is supposition. Slippery slope to stand on, when one puts one's self on a pedestal...
Fact is: a slob hunter is a slob hunter, regardless of what tool they're using. Carrying a bow does not magically makes a hunter more 'ethical', nor does the perceived self gratifying attitude.
Do you really believe unethical shots are not taken by archers?
Do you really think animals are not wounded/lost by arrows?
We all know there is an unfortunate side to hunting when things go afoul in the woods, is that really something you choose to base an ethics argument on?
Like I said, slippery slope when one chooses to play the 'ethical' card, and both sides wind up the worse for it.
We're all hunters.
Slobs are not limited to firearms, not by a long shot...
