"watch how he wipes his hands of the affair after someone dies..." Yes, it would be a pity if a nice, pink caucasian died, rather than one of the thousands who will die in the poverty trap... Whatever happens before or after this event, I fear that we will hear less about them.
Bob Geldoff and Paul Hewson will always be heroes to those who like them and villains to those who don't. The phrase,"that little shortass from U2..." (charming, when you think about it) is apparently supposed to persuade us that the man's opinions carry no weight, because he is below the required stature for his views to matter. I recall there were times when similar sentiments were expressed about the views of black people, gay people, women and the handicapped.
At the end of the day, The Curator is simply venting his spleen, because he dislikes the style of Bob Geldoff - I assume regarding him as a loudmouth, who shoots from the hip. He and his compatriot may have more in common than either of them would wish to acknowledge.
