Go home and grow up.

Just what is this protest outside St. Paul's in London all about?  All I've come across are vague pretty meaningless phrases like "corporate greed" and "economic injustice".  Like most protests, it seems its main purpose is to garner publicity by inconveniencing ordinary members of the public - in this case church-goers who wish to worship in St. Paul's and are unable to do so.  Pathetic!
