Seraphina, actually these  are nasty novus ordo tactics.  Novus Ordo did the same to our beloved priest.  In the end. Much worse. 

I can’t believe that the SSPX would lack true charity towards Mother Superior and Sisters.

Maybe they should kick out into the pedophiles and perverts from the society.  
Let’s face it the SSPX made a bad deal.  (I think the maronites made a better deal. )
