I have no objection to those who disagree with me making reasoned arguments in my comments and until now all comments submitted have been unmoderated. But there is always one who abuses the privilege and my resident troll has been getting steadily more abusive and strident. So much so that his last two comments have been deleted.
For the time being therefore I have reimposed comment moderation, because I can. Apologies to everyone else. Please don't be put off.
