Desperate times call for desperate measures and people run from OLOS to anywhere they think they can get a valid sacrament because they know that if they stay, they will surely lose their faith.
The OLOS parish is the meanest bunch of parishioners I have ever seen, and I have been in many SSPX parishes and Sede parishes over the years. I remember as a new parishioner there some years ago, most of the people wouldn't even say hi to you if you said hi first. They are a snooty bunch of fake catholics (for the most part), I call them modern day pharisees.
The main "family" there has had total control and influence over all of the priests that come and are the main cause of all problems. Between this family and all of the other families that suck up to them and do everything they can to be liked by them and "fit in", all cause the issues that continue to haunt the parish and school.
