"A peculiar virtue in wildlife ethics is that the hunter ordinarily has no gallery to applaud or disapprove of his conduct. Whatever his acts, they are dictated by his own conscience, rather than by a mob of onlookers..." A.Leopold
That is, of course, unless you open yourself up like an idiot to critizism. I invite folks over for dinner, serve them something out of this world, and then wait for them to ask me questions. You'd be surprised how many hearts are softened to hunting via this approach. Otherwise, I keep my mouth shut (it's a survival strategy in Comifornia) Sounds like that "hunter" needs some attention.
