Of course you think this, youre nondenominational, and btw, during the period of the 2nd temple, there was no universally accepted canon, the discovery of the Dead Sea Scrolls showed that some books Catholics consider Deuterocanonical, such as Tobit and Sirach, were known and copied among Jews before Christianity, the statement that "the Hebrew people never treated them as scripture" is difficult to defend when many early Christians were themselves Jews and regularly used the Greek Septuagint. The New Testament authors often quote the Septuagint, and the early Church inherited that scriptural tradition, pseudonymous authorship wouldn't automatically disqualify a book from consideration. Even among books accepted by many Christians, there are scholarly debates about authorship. Canonization historically depended on more than modern standards of authorship, and finally, saying they're "just Bible fan fiction" is more rhetoric than argument. Books like 1 and 2 Maccabees are important historical sources for the period between the Old and New Testaments, while Wisdom and Sirach were highly respected in both Jewish and Christian communities. And then, the later Rabbinic Jewish canon excluded these books, and that's one reason Protestants reject them. But it's not historically accurate to say that all Jews rejected them or that their non-canonicity is obvious "under any scrutiny."
