Thanks for the read! Yes, though to be fair to theists, I don't think the choice between responsibility and certainty is rarely a conscious one. As you say, it has a lot to do with cognitive dissonance, and a lot of it is subconscious and instantaneous: Travel down that path, and I lose certainty and possibly gain fear; therefore I'll stick with the path of certainty, even though that means I have to accept a lot of weird shit.
That being said - it will be interesting to note my highlight of responsibility here, and then compare that to a likely post in the future where I get into free will. :)
