We can’t improve on what we wrote four years ago, at least in terms of communicating the thought to people.
It was then, and is now, neither proselytizing nor advocacy of any kind, but simply an effort to explain an idea, on a day when perhaps many people seek an explanation of some kind. Our own opinion, for what it is worth, is that our reasoning faculty attests to the fundamental truths of religion and that atheism is ultimately irrational. On the other hand, the rational isn’t always true and the irrational isn’t always false, so there’s that problem.
Or maybe it isn’t a problem for this reader or that, or for us, or for you. Each individual can make of it what they will, a state of affairs with which we are perfectly content.
