This obviously had nothing to do with terrorism and I think such ancient buildings are more valued as cultural icons with little to do with current religious ideology. I'm sure that the French people consider this a great loss. There are many beautiful churches throughout America and Europe. We don't have to personally value or appreciate them to understand that others do.
I was relieved to hear that the building was evacuated before anyone was harmed. There are already several French billionaires donating money to aide in the reconstruction, which from what I've heard will take decades to complete. It's shameful that people like Glen Beck are trying to make this political, when the current evidence suggests it had nothing to do with arson.
