There are penalties for blocking or damaging churches.

"FACE" stands for "Freedom of Access to Clinic Entrances" Act. There are both state and federal versions of this law, and they provide draconian penalties for interfering with access to abortion clinics. But, as a sop to conservatives, they also provide the same penalties for obstructing access to or damaging churches. There are both criminal and civil penalties, meaning that you don't have to rely on the DA to file charges; if you can catch the person or persons responsible, you can sue them and get statutory damages and attorney fees.
