Why does it matter what your girlfriend's uncle thinks? If she is a good girlfriend it shouldn't matter. She should be understanding about it and accept the fact that you hunt. It's something you love to do, you have fun doing it, and it keeps you out of trouble. It shouldn't matter what her uncle thinks. If he bugs you about it, blow it off. I find it's a lot easier not to argue about it with people. Those who are against it are usually against it for the long run. You won't change their minds by saying it's fun, it provides food, etc. In their eyes it's murder and that's all it's ever going to be.

Just my thoughts.
