Having looked at the website, it looks to me as if this song has misfired in spectacular fashion if it is, indeed, intended as a kind of gentle satire.

...'emphasizing, of course, the generally productive nature of discussions with smokers about secondhand smoke exposure'.....

Eh?

Where exactly does this civilised and productive discussion feature in a song that comes across as a mean-spirited, angry, self-righteous and
just plain nasty tirade?
