Let's look at it another way:
A lot of large landowners will rent their land for corporate events.
Let's say that a group wants to rent a farm for a shooting event similar to TexasCowboy Shoot that FReepers have each year, should a farmer who doesn't like firearms be fined for refusing to host such an event?
Certainly not. Laughed at and mocked maybe.
Private property is just what it sounds like.
