comfort ye
Ok, we don't know enough about this. Usually, priests and sisters join with these people in protest of whatever it is. But if sacrilege is committed, are they protesting the Faith?
I'd be curious to know who's supplying the natives with sanitation facilities. I see turquoise"porta potties". Since that's diocesan land then the Bishop is within his rights to have such structures removed. The law might try to slow the inevitable removal of the squatters, but their departure can be encouraged by forcing them to eat, sleep, cook, and walk in their own filth.
