When a commenter continues to post questions which have been answered ad nauseum, refuses to answer legitimate questions that have been posed in response, and instead continues to viciously misrepresent a position that has been explained and defended at some length then it's time to realise that my time is being wasted and also that of my readers. As I've explained before:
I welcome honest argument and discussion. I welcome free speech. But the principle of free speech doesn't require that I provide my unhinged attackers with a microphone.Honest debate is welcome. Dishonest smears are not. That is all.
