Roger Scruton argues that political correctness, far from being the cure to our conflicts, is actually the ultimate source of them.
The "isms" and "phobias", he says, have been used in order to "put some complex matters beyond discussion, so that only one perspective can be publicly confessed to".
"In the world of political correctness", he writes, "there is no presumption of innocence, but only a hunger for targets".
