Sounds like you want to say no but are having a hard time with it because you have a hard time telling anyone no. While I hate to advise a land owner to not allow hunting, in your case you probably should say no. Everyone assumes that if someone asks you for something, you should say yes. It is human nature to want to help someone out. But no is a perfectly good answer in many cases too. If you really don't like the idea of someone hunting animals on your land, go ahead and say no. You will sleep better having done that.
