Given that infants do not have religion at birth, so that "regular" is the default setting, what's your best approach to helping a believer become "regular" again?
We don't actually know what an infant, at birth, believe or not believe. I'd say they can't believe anything since thought follows language but that's me.
You make a point. However, "thought follows language" may not be correct. Language communication follows language learning. Therefore, the ability to discern the validity of deity is also learned. Sadly, it may also be weighted by the teaching of one religion or another.
Beer until unconscious?
Pseudo skepticism until solipsism? The idea that nothings real its all an illusion.
We could raise our hopes a little that they might be evidentialists already and try to get them to apply that to all their beliefs.
Hope springs eternal. If they are raised with the practice of using evidence perhaps they can fend off the boogedy boogedy religious crap.
