Thanks for posting this. A few notes. The comparison with Notre Dame is wanting. The church in question (Vondelkerk) is not very old (about 100 years) and quite small. It has not been used for church services for years. So I find it hard to see this as an attack on Christian (Catholic) religion. My gut feeling about this event is that it was an inside job, likely perpetrated by the office of the (socialist) mayor of Amsterdam. The goal would be to generate a symbol of trauma to justify the prohibition of fireworks taking effect this year in the Netherlands. Part of the broader attack on traditions in the West.
