1. up to the conscience and the morals of Bono to lawfully arrange his personal tax affairs as he sees fit.
2. open to Bono to use his public profile to put his personal political views to the public

But, what is at the same time hypocritical, laughable and unacceptable is for Bono to have the gall to avoid taxes and at the same time chastise others (governments, individuals, corporations and supra-national bodies) for meanness in the area of aid and to hector others for loans to basket-case countries to be written off. Unless, that is, he does like Bill Gates and forms his own charitable foundation from his wealth.
