Proof that you lied? Okay, sure, that's easy.
You started a thread claiming that the AirTran MC was no longer coming to Dallas and was emailing AT pilots to tell them. I even tried to help you out of that one. I tried to warn you that it wasn't true, but you arrogantly assured me that "it's most certainly true". You only backed down later when it was clear that it was a lie.
Maybe you were just frustrated that night and won't do it again, but we have no way of knowing now, so it's hard to take anything you say seriously.
