On my citing William Goldman on killing a person with toothpaste
isn't a reasonable thing to do, I received a reply of "your
citing a novel?"

Yes.  William Goldman is a good author who researches his material
for accuracy before writing it (except in _The Princess Bride,_
which he didn't write in the first place  ;-)  If he writes that
killing a person with toothpast is unfeasible, I believe him.
Having read the ingredients list of a tube of toothpaste, it's
not inconceivable.
