Wouldn't surprise me in the least if they posted parishioners inside each doorway after these protestors exited. That way, if they tried to re-enter, I very much imagine they would be very heavily impeded at the door, this time. Churches are becoming much more savvy about dealing with people who come to intentionally cause disruptions.
