The moderator might ban religion (and politics and sex) from the list and
keep only the diet as a subject. The problem is that evolution figures
strongly in the paleo diet and every time evolution is brought up, the
nonevolution religionists bring up religion and dominate the time, even
though they appear to be a minority. It might be a bit more dull that way,
but less emotional and more diet-oriented---although I don't really like
the idea of banning.
