It wasn’t an offensive Christmas message, just odd.
I cannot find the Newsletter yet but it was a newsletter very offensive to MLK that also included a personal RP Christmas greeting. BUt somehow he still denies that he wrote it.
Finally, I found it: http://littlegreenfootballs.com/weblog/?entry=28537_Ron_Pauls_Personal_Details_in_Racist_Newsletter&only
IF the Christmas greeting was penned by him, it seems logical that he would want/keep a copy of that, even initially. The argument that he never saw these newsletters just doesn’t fly.
