It sometimes seems to me that one of the great changes of the past century or so has been the way piety has been appropriated by politics. Because most political narrative as espoused by the party faithful, apologists and enthusiasts is a kind of piety. It has been called political correctness, but for me, political piety is a better fit.
So in many ways the only real political divide is between political agnostics and the politically pious. Not surprisingly this is regarded with a certain amount of dismay by political agnostics who find the debate has taken on a wholly inappropriate holier than thou aspect.
Political piety has largely taken over what used to be the political left, but has crossed the traditional political divide as well as expanding into environmental, gender and race politics plus the more nuanced politics of victimhood.
Rational argument is of no value against political piety which in any event seems to be a global trend. It is becoming more difficult to be a political agnostic in a world where one is either politically pious or excommunicated – disenfranchised from the debate.
The three main UK political parties have all opted for political piety and will have no dealings with political agnostics except maybe a token maverick or two. Similarly with the BBC, most entertainers and most mainstream media, although a few prominent journalists are political agnostics.
There are alternative techniques for the political agnostic of course, such as ridicule and satire, to which political piety is rather vulnerable. Even so, the hugely ironic lack of diversity in political life will inevitably cause severe problems as the analytical deficiencies of political piety continue to rot away the fabric of our society and our institutions.
