Even in the non-technical sense, he's still making a relevant counterpoint, because it's much, much harder for atheists to go without exposure to religious culture and arguments than for a religious person to go without exposure to atheist arguments or culture (insofar as such a thing can be said to exist.)
I don't just mean being exposed to religious culture and arguments, I mean good arguments. I know, practically everyone here was raised religious and given really bad reasons to believe. But I think those may become a straw dummy—what I'm skeptical of is how many people here have heard a religious argument that actually made them think, one that has a chance in a real debate.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
