Well I suppose I’d be kind of mirroring what I said in the question that inspired this one. I don’t regard myself as a “theist”, but as a deist.
Would I consider regarding myself as an atheist again? Quite possibly. It would be arrogant to write it off as a no. It is possible I could.
Now what I would expect is a reasonable argument against deism and the most common modern deist concept of a deity. I won’t expect evidence as I don’t expect an atheist to disprove God. But a reason based argument might do the trick. It would have to convince me that the God of deism has a very low probability of existing.
Although one thing that has been said about deism is that it is an undisprovable hypothesis.
