No one is taking her 'parish community" away. If there is negativity and anger, it's likely coming from some of her own friends who don't like the changes the priests made.
As far as the school is concerned, it sounds as though the people in the Parish got their behinds on their shoulders about the way the new priests are saying Mass, and they are punishing the kids in the Parish by not supporting the Parish school.
And as for the man who says he's not saying anything 'untrue' about the priests, one can speak the truth, but do it in such a nasty way as to create suspicion about another person, or cause others to have a negative opinion about that person, thereby harming someone's reputation. That's CALUMNY, and it is as sinful as lying about someone.
