“I ascribe infallibility to only one Being… and it’s not Chazal.”

Who said anything about infallibility? That’s your fig-leaf. They are far closer to infallibility than anyone since. And therefore no one since has any right to dispute them.
And “malochim” was descriptive, not literal. You should have (and perhaps did) known that.
