Notre Dame isn't some confederate statue erected in 1970. This was a world history site. We won't get it back. It's a tragedy, let people grieve. We know the RCC was shit, we know France was shit, but Notre Dame wasn't entirely shit. I'd cry if the Taj Mahal collapsed or if the Hagia Sophia was destroyed, it's not all about religion or the West or whatever you want to make it about. Sometimes it's just about the art and history itself.
All of civilization, all of the things we do on this earth are temporary and mortal and it is painful to admit so. Nothing lasts forever, not even these things that feel like they've been here forever.
