Why would they want to Target the diocese, they have trashed the kids just as bad as bad as the media.
Goes to show, the left is never appeased. The diocese could just as well have kept their principles and not sold their souls.
There is some speculation that Liawatha recognized some of this kids from the group from when he harassed the national cathedral. So maybe the church attendees who just happened to be the kids were his target.
IMO, they either want to "send a message to the Catholic diocese" or start riots around the nation - another Crusade of sorts.
Thankfully, most Christians are peaceful people.
