If in order to pay the mortgage or taxes on that hall you need to rent it out for weddings then you will either have to allow gay weddings to take place there or risk having your hall sued away from you by the first gay couple that comes along.

If everybody else can demonstrate in front of the state houses or city halls, what is so difficult about getting a whole Catholic, Protestant or Jewish congregation out in front of the state houses or city halls en mass? We have larger numbers than they do. The politicians have to decide, do they want 2% of the vote or 98% of the vote?

People who want to brush aside social issues are fools and are not worthy of our vote!
