Hi Michael, thanks for the reply. Here's how I see it:

“I met a local sample of hostile Christians. Therefore, Christianity is invalid,” is anecdotal evidence, not a falsification of historical or metaphysical truth claims.

Personal experience has no epistemic reach into whether God exists, whether Christ is risen, or whether Scripture is reliable. Invoking Occam's Razor on the basis of anecdata is a category error.

Such anecdotes are unsurprising as well, unfortunately, given Jesus Himself warned of widespread hypocrisy, explicitly stating that the church would contain "tares among the wheat" (Matt. 13) and that many who invoked His name would be revealed as “goats, not sheep” (Matt. 25:31–46). The existence of hypocrisy in the faith is a feature of Christian teaching, not a refutation of it.

Consider this medical analogy: I've had several terrible doctors throughout my life. Should I conclude that the entire medical profession is invalid? Of course not. Incompetent practitioners do not invalidate the truth of the discipline they claim to represent.
