Thank you all for your input and exchanges, they are indeed quite helpful.
Firstly, I'd like to say I have no desire to sue the Library, this one or any other one. "Libraries" are buildings with cataloged media inside, available to the public. I volunteered my time, and donated my own personal resources including Books, VHS's, DVD's, Books on tape, and even cash. I don't want to see that hurt, or left unable to perform it's duty.
'I' want the Library to be what a Library is supposed to be. My Director and the Board want something different. The Board President told me point black, that a local library should be at least in part, "a reflection of the community's standards, viewpoints, and interests", whereas 'I' thought it should be a "window unto the world, unaffected by the local biases and viewpoints".
Our meeting room is empty most of the time. In fact, besides our group, there was craft time that takes place every Tuesday morning, and the Library Board which meets only once a month. And the Boy and Girl Scouts that use the room once ever 2 or 3 months! When I volunteered, I was always 'trying' to get the room booked, otherwise it is just a wasted resource.
Our group has decided to circulate an un-official petition, humbly suggesting that anyone working in or with the Library take an oath of office to promise to protect and uphold the American Library Association's "Library Bill of Rights"

The last of which would cover our group's activity:
"VI. Libraries which make exhibit spaces and meeting rooms available to the public they serve should make such facilities available on an equitable basis, regardless of the beliefs or affiliations of individuals or groups requesting their use."
After we've collected a few signatures, we'll submit it to the City Counsel, along with an offical complaint that we feel as though we were treated 'differently' than any other group, and that the Library Board violated or abandoned their own policy regarding the use of such facilities, in order to deny us access.
I asked questions about a possible suit, because I just want to be prepared for any eventuality. I am beginning to doubt seriously that our little petition will have any positive influence. I fear that I may have to threaten suit, to make them believe this is serious, and maybe even file, if only to make them offer us a 'deal'... Who know where this will end.
