The money from the fountain gets collected and sent to Caritas, a catholic charity that focuses on health, disaster relief, poverty, and migration. I am a Queer atheist person in Spain that uses their services and they haven’t once made my queerness an issue. Nor have they exposed me to their religious views.
So, shrug, I’m not gonna shit on them doing the tradition that many diplomatic events in Rome do.
Objectively, it sounds like it's an innocent tradition and a healthy charity.
Subjectively, it's tone-deaf af, when the rule-makers perform superstition for such a massive world-changing problem. Basically "thoughts and prayers."
A friend once applied for a job at Caritas in Germany and got rejected for the reason of not being catholic, but christian. I think you could argue that is okay, but by German law it actually is not.
I realy don't understand why the church still gets to do so many things that are simply not legal. It seems like the law that they have to follow is an older version.
My aunt works for Caritas in Germany. They do seem like they do good work, even if they believe in the whole resurrected vampire man who was birthed by a virgin and impregnated by a dude who flooded the world for fun.
