If Jane inferred from your username that you were a QC then she isn't lying. You may believe that her inference is misguided. You may also believe that her inference is stupid and it is fair to say so, but it is an over reaction on your part to keep calling Jane a liar over a misunderstanding.
I do not get on at all with Jane and have had crossed words with her myself but you are unjustified in calling her a liar because she believes that your username implies that you are a QC.
Sorry but you've not got your facts right, Gringo.
Again, you're not reading all the relevant posts because you've missed two points:
1. First, before calling her a liar, I corrected her and explained why I use the initials QC, which is to do with me personally.
She ignored this and repeated the slur.
2. Second, you've also missed that I called her a liar because she lied about knowing somebody connected with the case, or if she does know that person, she lied about what she knows. She did this to blacken Jeremy Bamber. Now, I remain neutral in the case, but I take the view that blackening him only contributes to a faulty understanding of the case.
