Re: "Hunting Must be Banned"
There's a couple of things to address- Safety is #1. Start by pointing out the statistics on hunter safety and that it's a very safe sport, do some research to determine if any dog walker has EVER been hit with shotgun pellets. Point out that clearly the hunter was cognizant of safe hunting as he held fire when he noticed it wasnt' safe.
Definitely hit the "modern people dont' need ducks to eat and shop at grocery stores" BS by pointing out that you as a hunter supply your family with wild, free range organic meat, as this meat is healthier and lower fat than any other.
Point out that hunters strive to clean up after themselves, including shotshells and IIRC there are yearly :clean ups" done by hunters in the area that target not just dropped shells but lots of garbage left by other user groups.
Are the dikes for people to walk on, or to hold back water? Point out that hunters were there first and are more than willing to share with all user groups, and hunting only takes place a few months per year.
Definitely get some actual numbers of dollars generated by waterfowl hunting groups to fund waterfowl habitat preservation
I'm not familiar with the area but it's possible that some time in the past hunters fought to maintain habitat in that area, too.
Be sure to point out that the "duck remains" in the picture are simply some feathers and bone that are left to return to nature after the hunter removes his free range, unmedicated organic meat.
I dont' know the area, I'm sure some locals cold flesh this out a bit, but these are points I've used successfully in the past.
Knowledgeable shooters agree- The 375 Ruger is the NEW KING of all 375 caliber cartridges. ALL HAIL THE NEW KING!
