All the pastors should have a press conference and state that they do not block anyone from entering their churches. If the city officials want to see/hear what is in their sermons, they are more than welcome to attend the services.
How about daring Annise Porker to send in her goons?
I agree.
They could also, very publically, extend personal invitations to city official to attend services when sermons on homosexuality are going to be preached.
