The last sentence was a clumsy attempt at an axiom and a conclusion; I was rushing when I wrote this so the comment would be there when somebody got to the end of the post. (In retrospect, I really should have written this -before- I posted the article.) Indeed, everything except the last sentence I ended up copying from my blog, because I realized it would be faster than trying to rewrite the logic from scratch. I omitted several pieces of logic that the blog contained in my haste, however, including the conditional that the current state of legal affairs about leaving infants exposed to the elements is desirable.
