If you're planning to sing this song, I recommend you sing it exactly as it appears at Bogle's web site. No doubt that's the version he prefers now, although he may have recorded it differently in the past.

I suspect he deliberately deleted the "strong lines" you are referring to because they are--to put it bluntly--demeaning.

Think of it this way: How would you like it if someone said of you that you were "finished" and that you were living in a world you couldn't understand?
