The irrational expectations of atheists

Some atheists claim that the theist must prove the existence of God to them in a way that they (i.e. atheists) find convincing, if the theist is to be considered rational. But this is an irrational expectation as Brian Leftow points out. Of course, there are proofs of God that some philosophers find convincing, but as in all matters philosophical there is never complete agreement, which by implication is what such atheists demand. On such a basis, then, nothing could be considered rational, unless everyone considered it rational. Or to put it another way, anyone would have a veto on what could be considered rational, on the basis that they were not persuaded.
