I cannot enter the debate as to the relative desirability of that delicacy contrasted with others, as I have never had the courage to get close enough to it to know what it smells like, much less tastes like.
I do, however, have a certain amount of expertise when discussing other qualities and effects lutefisk might have or possess. You see, I presently live within about 10 miles of Three Mile Island, of "Three Mile Island" fame, and have duly noted that those present here back in (?Was it '79?) are not quite right in the head. The universal theory is invariably lumped into one big generalization with a knowing nod between the cognoscenti and the simple statement, "Toxic Waste" when two normal people witness the way one of these vets of that incident roll through life...Don't get confused though, their conversation just went nuclear.
I have a very similar theory as regards our Minnesota Norse friends.
I believe the literal translation of lutefisk is "Cod soaked in plutonium".
Now to me that explains a hell of a lot, your intrepretation might vary.
To be fair, I recall being warned not to engage in a certain activity or "I would go blind" ...Of course I ignored this advice, at least until I needed a very heavy prescription, and thank God for Lasik. All in total jest, btw.
