I've had a long and interesting discussion with a "non-hunter" about this on FB. (A friend, pro-hunting, posted it, so we've been crapping all over his wall. )
He can't understand why some would think that "fun" = "I think I'll go out and kill something this weekend."\
Plus, I wish I could find it again, but the was a graphic (maybe more than one) that showed the populations of various African animals both from like 1960 and now, and those nations that allowed hunting showed dramatic increases in populations, while those that banned hunting showed dramatic declines.
