Just by chance I picked up this on the net. It is from a book called "How to win arguments when you have no case" by someone apparently called Tony Bliar. The book had been roughly handled, only scraps remain legible, e.g.
"Stop answering questions. Better still, invent questions you would like to be asked and answer those
If pressed, try and change the thread to something else
If criticised take the moral high ground. Adopt an air of injured probity
Categorise you opponents as childish and unreasonable and all criticism as unwarrented abuse.."
