On the whole I generally agree with the statement, but my form of atheism is the same way I try to treat all truth claims IRL.
The "tests" I do to test against the "No God" null hypothesis are very much in line with your statement about "a diety with those attributes". I fail to find sufficient evidence. It could be, though, that I am incorrect or missing something quite key. Which is why I prefer the more logically robust position of weak atheism.
I fear that some on here like
@Cypress or
@Ross Dolan wish to debate the existence or lack of existence of some ineffible, perfectly unknowable being which is dangerously close to "unfalsifiable" for my tastes. As such it is easy for them to be perfectly agnostic as there is no value to the truth claim they are testing at that point.
Of course no one can know something that cannot be known. But if something can be known, even hypothetically, it is liable to be testable. And for most people their conception of God has very real aspects rather than being a fuzzy unfalsifiable meaningless concept.
