"People say things and put things in different ways and everyone knows what they mean. Those who chose to use others choice of language as a weapon, quite rightly, have the piss taken out of them and soon find that no one will engage with them. You are getting very close, Nigel."

I am afraid I do not agree with you. There are no people posting here that are not capable of checking facts, or phrasing their postings with a minimum of ambiguity.
There is no excuse for making statements that are demonstrably untrue, or for trying to put forward opinions as fact. Trying to wriggle away from responsibility by claiming not to be a lawyer, so sloppy presentation is quite OK, is a total cop out.
I always endeavour to be clear as to whether I am quoting others, stating facts,or offering opinions. I could not care what opinion a   poster may hold, but inaccuracy and opinion trying to masquerade as fact do provoke a reaction. People may well say things in different ways but that is no excuse for ambiguity that leads to argument.
I can only react to what people say, it is the responsibility of the author to say what they mean.
