JJ, takes a lot of courage to 1, not get sucked into that mess...2, to come here and share your thoughts.
I was brought up in a hunting family that occasionally bent the rules. When I was young, I may have bent a couple myself. Back then we had "party permits" for doe...it is exactly what it sounds like, 2-3 people on 1 doe permit. You had to decide who had it for each particular "sit", so only 1 doe was taken. Today, with all of the permits available, there is no need to not tag a deer. As I sit here today, I can legally shoot, 1 buck and 4 doe during gun season. I know not all zones are this liberal, but still, everyone usually get a least 1.
Sounds like your people "get off" on breaking the game laws while killing deer...That said, unfortunately they are not the only ones. My advice, be honest.....tell your dad how you feel. He may not change, but also may respect you for your convictions.
