Why not use "slander" because that refers to spoken word not written word. The definition I use for libel is the first one that comes up in a widely used English language dictionary, I would suggest that that means it is widely understood in our society to mean "a piece of writing which contains bad and false things about a person". Perhaps the CPGB should publish their own dictionary that deals with their own social context. There are different kind of rationalities to be sure, but anyone that doesn't understand the right of a nation to defend itself against an aggressive neighbour that keeps issuing threats, probably fails all definitions (save the CPGB's own) of rationality. Refusing to condemn is not the same as supporting. I would not condemn the police if they intervened to stop a case of domestic violence, I don't support them because they are the police. Maybe Lawrence and Jason would condemn them or maybe they would support them?
