Now Fox News is reporting on this.
https://www.foxnews.com/politics/pro-abortion-groups-target-churches-for-mothers-day-protestsSomething very important to know and consider is that militia-types and other volunteers might show up at a chapel to assist with security. The chances of this obviously increase with an outbreak of physical violence and the longer the situation takes to unfold.
This is a situation that should be left your parish priest to handle and taken case by case.
We can't let unstable people around us with guns and have them escalate a situation. Yet we also want to be welcoming to those who want to help us, and far more importantly, give regular sinners the chance to fight for the Church as an act of charity, this might be how they find salvation.
If help is accepted from non-Catholic volunteers, they should not outnumber the Catholics and they must be subordinated to Catholic lay leadership, not just the parish priest's.
This has been our fight, and this struggle needs to be our thing, don't let outsiders take it.
An outsider can take your struggle if he appears to be more effective and authentic in waging it than you do. Don't let this happen. Never let a non-Catholic volunteer speak for us either. Be thankful for their help and keep them in a position of subordination.
