Do you write comments on newspaper articles online? You shouldn't.
I very rarely get comments on my Blog posts – and for that, I am very grateful. The problem with online comments is that no one is listening, and everyone is talking; it is a world where people scream their opinions into the abyss with an obstinate certainty they would never display in real life – there is no persuading anyone of an alternate point-of-view because everyone's positions are already so entrenched, and ad hominem is the default approach for making any point.
No one can ever 'win' one of these arguments (read: shouting matches). I don't think anybody is even trying to. There are plenty of comments on this critique of Russell Brand's latest book by Michael Moynihan, most of which are pretty hostile – and yet there are precious few attempts logically to refute the arguments the author makes, and instead the commenters' points are almost all "you're jealous of him!" or "you're just a stooge of 'the establishment' anyway!"
I've lost count (OK, I was never really keeping count) of the number of times I've read an excellent article, followed by a bunch of moronic comments from people with no interest at all in debating the issues raised in the piece with an open mind.
So, let's all try to restrain ourselves, and stop posting comments – the world will be a happier, nicer place for it.
