To avoid turning people against hunting, it is advised not to display vulgar or obnoxious bumper stickers or slogans. These kinds of messages can alienate non-hunters and create negative perceptions of hunting. Responsible hunters should also avoid bragging, starting arguments, using foul language in public while identifiable as hunters, wearing bloody clothing, displaying dead animals publicly, disrespecting landowners or private property, and any behavior that could be viewed as disrespectful or offensive to the non-hunting public.
In summary, avoid bumper stickers and slogans that are vulgar, obnoxious, disrespectful, or offensive, as they may create animosity and turn people against hunting.
