Well 9pointer123,
I hope your girlfriend is smarter than her uncle. I have a cousin who thinks the same way. She supposedly is an animal lover, and basically what I tell her is if she really cares about wildlife then the most beneficial thing she could do for the wildlife is to buy a hunting license and get into the shooting sports. I tell her that she doesn't have to actually shoot anything, but if she wants to put her money where her mouth is, then at least buy a hunting license.
Click on this link and read about the Pittman Robertson Act, and you will see why. Print it out and show it to her uncle, and you will probably see how closed minded he is
