I don't know BillardBall's thoughts, but I recognize something as a skeptic. For all humans for all times and all cases of different contradictory claims, not just about gods, you get that 99% of all humans properly were or are irrational. But that is absurd, because it becomes normal. All normal humans are irrational, so now what?
There is still a humanity, babies are born, lucky people have lives, have children and live good lives if lucky.
Further in an even more absurd sense, to claim to be rational is how weird it might sound a case of special pleading.
Now for this version of rational, based on facts or reason and not on emotions or feelings, I have found it impossible to be rational all the time. And i doubt any other human can do it, including you.
