It also looks to me as if Giles Fraser might usefully reflect on these observations concerning the difference between toleration and relativism:
In the intellectual world, toleration is the disposition to fight opinion only with opinion; in other words, to protect freedom of speech, and to confront divergence of opinion with open critical reflection rather than suppression or force... Relativism, by contrast, chips away at our right to disapprove of what anybody says. Its central message is that there are no asymmetries of reason and knowledge, objectivity and truth... It is not only that we must try to understand them, but also that we must accept a complete symmetry of standing.That is a passage from Simon Blackburn, courtesy of Ophelia at Butterflies and Wheels.
