WhatsaLizad?: There are clear instructions for all participants of PPRuNe, which is to discuss the subject and not impugn the person themselves, no matter how much you dislike what they are saying.
1) I made an observation.
2) You said that it had been disproved.
3) I pointed out what I had actually said, showing that I had said something different to your assertion. This demonstrated that I had not been 'disproved'
4) You insult me.
That is not how things are done in PPRuNe.
