No, that’s not what I mean. There were accusations - and I think well founded ones years ago about French priests in the SSPX spewing anti-American vitriol at Mass and in their teaching.

Srsly.... ++Gibbons was one of the most heretical prelates in the USA since +Ireland... He made Cardinal Mahony look like a choirboy... yeah... I couldn’t even get past the first essay, sorry.
Whoever wrote that has no idea who Cardinal Gibbons was, what Americanism is, and is certainly ignorant of the struggles going on within the American Church up until the Great War, I’m uncertain whether this is an intentional or not.
Your links are nothing but ancient, third-party hearsay. The SSPX has reams of publication on the internet but you have not provided any credible source to back up your accusation about what it professes.
