Most of Peter Larson's claims (in my view) are incorrect.  But let's be
fair here.  He didn't just make his claims up - he had legitimate reasons
for each and every one of them.  They weren't just "misleading."  I
disagree with him on several points, but I do not for a minute think he was
inventing observations; I would only go so far as to claim he was
misinterpreting some features - an accusation many have levelled against me.
