I think it got deleted. It was a response to the Paul Ryan/Ayn Rand article conversation. I can't find it. I can find me referencing it in emails to others. Not the original. I don't think it's worth some forensic reconstruction. Something like that was said, the exact words I don't recall, and you wrote a very impressive apology letter the next day. It was definitely soon after that date. The apology letter, I recall thinking, this must be how lawyers tell people to apologize, it was good, no excuses, no you provoked me, nothing like that. Rarely seen someone apologize so well.
So, I guess unless you really want more proof, you will have to just believe me.
