I would broadly agree with the thesis that violence engendered by differing interpretations of religion is going to remain a significant feature of terrorism and armed conflicts around the globe, but I am less certain that I would agree with Mr. Blair and his faith foundation.
What would worry me is that, in his desire to promote religious tolerance, and respect for religious differences, we see the implementation of laws designed to shut down criticism of religion, using those twin arguments of "lack of respect" for someones religion, or even blasphemy.
We can see this played out in microcosm in this country, right now. Maajid Nawaz, the founder of the Quilliam Foundation, an institution set up to combat extremist religious ideology, recently tweeted a cartoon of "Jesus and Mo", the subject of the cartoon being Jesus and Mohammed greeting each other ( Hi and Hello speech bubbles). Mr.Nawaz also happens to be a prospective parliamentary candidate for the Lib Dems. An activist within the Lib Dems complained that this inoffensive cartoon was "blasphemous" and an insult to the prophet, and started an online petition calling for the deselection of Mr.Nawaz, which has gained at least 20,000 signatories.
Mr. Nawaz himself has received innumerable crude insults and several death threats over his actions in tweeting this inoffensive cartoon.
