Misconception #1:

   [a free market]  The only way that irradiated food could be forced
   on them is if all of the non-irradiated food is pulled from the
   shelves, which is probrably not likely to happen.

In the absence of labeling laws (which you go on to endorse), we have
fraud, rather than a free market.  For example, if the spices you put on
your food are not explicitly NOT irradiated, they probably are irradiated.

Misconception #2:

   ... no labels on pesticide-free food saying that "Out of your
   squirmishness about chemicals we let the bugs eat part of the crop
   even in a world where people are suffering from lack of food.

We have the food to feed everyone a sufficient number of calories to
keep them healthy, even if we let the bugs eat part of the crop.  When
people starve, it is because of political problems, e.g. Ethiopian aid
rotted on the docks while the soldiers kept it from the starving
people.

Before I got into solid state physics/electronics I worked for a number of
years as an aqueous and organic solution chemist (undergrad in chem from
UCSD).  I specialized in photoactivated nitrenes and modifications to 
proteins (enzymes) with various cross-linkers (which we synthesized).
I would be very interested to see the citations in Chem Abstracts indicating
work done that describes stereoisometric inversion of chiral molecules
achieved with microwave radiation.  I will buy such rearrangements with
UV or higher energy forms, but microwaves? (just the citations, please).

for evidence of absence."

  I think it's time to add my 2 cents.  When you irradiate anything with
ionizing radiation (which is what irradiated food is), just like anything else,
ionization of the molecules and atoms takes place.  IT IS ENTIRELY POSSIBLE
that this can break bonds and cause new ones to form when the electrons fall
back into place.
  But remember, this is with IONIZING radiation (X-Rays, gamma, and some short
wave UV).  Microwaves DO NOT cause ionization, and cannot cause new bonds to
form from processes other than thermal.  Microwaves are only radio waves, the
the most they do is cause currents to form and cause resistive heating (which
is how microwaving works).
  Now most of this group probably knows this already.  But I thought I'd just
bring up the facts, just to be sure.  Microwave food doesn't scare me anymore
than my 2M handheld VHF radio and microwave dishes on top of "radioactive"
mountain transmitter sites.  Mike

Fairhaven College is small "cluster College" of Western Washington University,
which features an interdisciplinary curriculum straddling the humanities and
sciences.  Its motto is:  "non-competitive excellence."

Isn't this an oxymoron?
