I think you'll see formerly religious atheists make the most claims about the illogic of (their former) religion, because they are most familiar with it. They can provide logical arguments against their particular former belief, but none that would ever convince the true believers (e.g. those who say things like, "Even if the Pope said tomorrow it was all a sham I would still believe in Catholicism", or similarly for other hierarchical religions).
Your mention of axioms is very similar to how I used to reason about my own former belief. When empirical reality contradicted those axioms and I spent some time away from the continuous reindoctrination to examine what I believed was real, I found it far more reasonable to disbelieve than to replace one belief with another.
Ultimately empirical reality has to be the arbiter; no amount of soul searching alone, without evidence, can reveal facts about reality. So maybe there is no concrete logical "proof" that physicalism is real, but empiricism isn't about absolutes, and empirically, physicalism has a much, much better track record of supplying new, true knowledge about reality than any other supposed way of knowing.

To reiterate, I believe strongly in empirical evidence. I'm mostly arguing against it being the sole source of knowledge.
And thanks for sharing the rest of your thoughts. I would call what you believe about physicalism a form of faith since you are aligning your expectations to a system that has a good track record in your experience. And I think that's understandable.
At any rate, if we can have a little humility in admitting the limitations to our own certainty, I believe we'll have more charity when dealing with people from other perspectives.
