If the issue is parking why don't the neighbors talk with these people. The article says it's only 7 adults so the most we're talking about is 7 cars.
I suspect there is something else going on. Maybe the ethnicity of the Christians or the enthusiasm of their worship. It doesn't really matter. If I don't want the govt telling me who can come to my house I shouldn't allow the govt to tell someone else who can come to their house.
If the issue is parking, they need to outlaw Mariachi parties and Superbowl get togethers and weekend BBQ's and family reunions and while we're at it, lets tell all the neighborhood kids to stay indoors and quit playing street hockey and hide and seek.
This is religious discrimination, plain and simple.
