As with the current president, MLK's life story stands on it's own as exceptional and inspirational, without embellishment. He did not walk across the reflecting pool before the "I have a dream" speech, and there is nothing in the record about him being a sci fi fan. Certainly Gene Roddenberry would have contacted him after Nichols asked for her job back or at least referred to this story at some point in his life. As far as I know, he didn't. Thinka about it: Roddenberry was a liberal (or at least a libertarian). This would have been the biggest thing that ever happened to him. Doesn't pass the smell test.
I checked out that website google.com for a medical term for people who make up stories to implant themselves into history and place themselves at historical events (like the five million baby boomers who say they were at Woodstock, or the 2 million Yankees fans who say they were there for Maris's 61st homer), but I failed to find one. Having done so, I feel free to coin the term "pulling a blumenthal."
It is hillarious that my post follows yours.
She was nice to me, at least.
