I had a liberal tell me to my face that there's 'my truth' and 'their' truth', and other people's 'truths'. Astounding, and unclear on the definition of 'truth'.
Ergo, if something happened, and if you don't believe it happened, then it didn't happen. The person whith whom I had this discussion is otherwise intelligent and creative, and a nice guy overall. He's just got this intellectual disconnect where things involving logic are concerned.
