Wow, that scenario is so sad.
How far away are they from their hundred? Do you have any idea of the general consensus of the chapters on campus? Perhaps if they are a minority, they could somehow be shamed into silence by the other chapters? (IMHO, they should be ashamed that they are even thinking of doing that! What a horrible thing to do, kicking a chapter when its down!)
