When teaching Hunter education classes, I highly emphasize the importance of not flashing the success of your hunt, or the tools you use. There is no reason to show a bloody animal to someone who may be offended. The quickest way to turn someone who doesn't care about hunters into anti hunters, is to sit at a stop light with blood running down the back of your truck.
These morons are hurting not only themselves, but the many responsible sportman who follow the ethical rules of gun ownership. These people are not responsible gun owners, they are mentally incapable of having the right to own anything that can be used to harm others. Just my humble opinion.
