We might learn a few things from the fundamentalists' talent for not compartmentalizing.
I've long said that the only religious people I can converse with are the fundamentalists, as they at least acknowledge that truth exists. They may seek it from their holy book rather than bayes and occam but at least they acknowledge it. The 'liberals', when pressed hard enough, tend to go into some kind of relativism that really negates the entire notion of 'conversation'.
Based on the community's continuing interests in diet and religion, I'd like to point out this blog post by the coauthor of Protein Power, Michael Eades, wherein he suggests that biblical literalism tends toward a low-fat approach to nutrition over a low-carb philosophy, by essentially throwing out a bunch of evidence on the matter:
While there's a clear persuasive agenda here and I won't present a full analysis of the situation, Eades also mentions biasing use of language earlier in the article. In particular, beware applause lights and confirmation bias in evaluating.
