That is true in my experience. I find it somewhat frustrating that I have to argue by picking apart the Bible and defending evolutionary biology instead of by talking about reductionism and Kolmogorov complexity, but the former is what seems to work. (Quoting myself from elsewhere: "I find that deconversions begin more often from a person noticing some internal absurdity in their beliefs than from having the problems in their epistemology explained to them. It’s only once they find they can’t run away from some counterexample to their beliefs that they are willing to consider why such a counterexample is allowed to exist.")
