French necessarily aren't infees. If they converted from Catholicism then they'd be fine under the ORRA structure - I wonder if that did happen in Keybeck, all the pure-blooded Francophones converted en masse like the Jews in SpainNah, because NUSA idolizes Rome-they think it became Inferior after the Western empire fell and that it’s modern descendants (barring Protestant French) are Infee’s, but Rome itself (as well as Ancient Greece) was awesome. The US in OTL took a lot of Roman inspiration and loved classical Greece and Rome well for a long time thinking of modern Italians and Greeks as racially inferior-this is just amped up a ton TTL.
I’m not sure who they’d blame for Jesus death (if anyone). The Supercatholics and such would definitely blame the Jews but that stance is probably getting a lot less popular in Europa. However, I don’t think blaming “Latins” would be popular in Fundie nations either.
As for Rome and Greece, they probably say that all the repeated invasions by eastern barbarian tribes plus the muslim settlement from Turkey destroyed the "ancient pinnacle blood" of the Romans and Greeks.
