I am an avid hunter and fisherman and I hear it all the time; bloodthirsty morons who just really need to kill something but attempt to justify it, so they claim that everything is a threat, a pest, a menace, blah, blah, blah. I see nothing wrong with killing an animal or fish for food, or for protection of self or property, but killing something like a bowfin or a gar simply because it might eat some of the fish you want to catch and eat yourself is pretty sad. Can't compete? Stay out of the fishing game, or get more skillful at it...don't set out to eliminate what you perceive as "competition".
