Freedom from religion

[brewer]

Then the church needs to stop renting to persons/entities outside their church or denomination and make that clear in their advertising.  

If they do rent to outside persons/entities then they open themselves up to discrimination suits (which apparently they have).

So what's more important, convictions or money? If they take the money or make an agreement and make no religious stipulations in their advertising and then say "no" they should be bitch slapped all over town.

And what if it has nothing to do with LBGT issues? Must a parochial school rent its auditorium for a divorce party?

If the parochial school rents to the general public, makes no stipulations in their rental advertisements/agreements and does not inquire as to the nature of the party, then yes. 

There is this thingy called "due diligence". Due diligence needs to be applied in the face of their convictions.

Edit: If the school/church has a history of rentals to entities that do not hold their convictions, the school/church has opened the door and forfeited their right to say no.
