If what you claim is true, then perhaps you can explain to us why he so often sucks up to Islam.
We’re waiting.
I do not believe the Prince has any special interest in Islam as compared to other faiths - he's a member of the Church of England and he takes that faith more seriously than any other, though I don't believe he's particularly devout, but beyond that he simply seeks to treat all faiths with respect. Being respectful towards Judaism, or Hinduism, or Buddhism, is completely non-controversial and so his gestures in those directions don't get publicised. Being respectful towards Islam, however - well that creates some controversy and that sells newspapers and ad space on TV - so that gets stressed by the media when it happens.
The Prince has no time for terrorism in any of its forms - but I'd point out to you that his own Godfather was murdered by terrorists who hid behind Catholicism as the basis for their crimes. He makes a distinction between the actions of fanatics and those who merely seek to follow their own faith in peace.
