I've seen news of churches (Catholic, as most Churches are in France) been set on fire maybe 2 or 3 times in the news here in France, that was a while ago... Not seen any news like that recently. Are there any sources about the true numbers of these arson fires ?

I had the same conversation with someone living in the US at the time of the Notre-Dame fire, I couldn't come with more than 2 or 3 occurrences reported in the French press naming specifics cases with places names and all, while he, in the US would provide me with dozen of press reports of "Churches are burnings by numbers in France !" type of titles ... Many from a very specific side of the political spectrum.
