... So AD 100 is your arbitrary date for where Christian practice "went off the rails."

No. It the time of the last living Apostle. If it wasn't taught by apostles or included in Scripture by Apostles, it is false.

...To believe that, you have to assume that all of the relics of the Apostles that exist to this day are frauds. Is that correct?

No. You have to assume they should not be idolized, prayed to, bowed down before, etc.

Nobody does that. Asking the Saints to intercede has nothing to do with "idolizing" their relics. That's a faulty Protestant definition. Y'all miss out on a lot of graces by rejecting the intercession of the saints.
