Whilst clearly (and inexplicably) a great ambassador for Islam, he contradicts himself somewhat in extolling the dubious virtues of what he sees as that religion's supposed intrinsic understanding of nature. At one point in his speech, he says that the increase in world population is detrimental to the natural world, but since Islam's adherents are among the worst offenders it's abundantly clear that he hasn't really thought this through.
In his seemingly unswerving praise he speaks of Islam's 'noble heritage', but that, in my opinion, is something that, along with its dignity, Islam has in recent years voluntarily abandoned. Whilst his emphasis on the benefits of looking to the past and to the spiritual could possibly be seen in some ways as commendable, his clear admiration for religion and the ancient superstitions surrounding it do absolutely nothing to promote progress. In fact quite the reverse. Organised religion is the biggest threat not only to the free intellect and to the self-respect of every human being on this planet, but to the survival of this planet itself. These are the idealistic words of an unqualified and greatly privileged man who is purposefully and continually cosseted from the real world - so yes, I think he probably should keep 'mum'.
Incidentally, on his accession to the throne he intends to become 'Defender of Faith' rather than 'Defender of the Faith'.
For anyone who's interested, here's his speech.
