So, I read the archived article, and first, I have to take issue with:
"The first interracial kiss could have actually happened on 
My Mother the Car, but no one would ever know, because there haven’t been 
My Mother the Car conventions happening steadily since the 1970s, where cast and crew can reunite and tell the same anecdotes over and over until they become generally accepted truths."
And I want to know how the author knew Jerry van Dyke kissed Cicely Tyson on the lips in episode five but didn't think to post pictures...
(I'm kidding -- that never happens. And, God's truth, I've seen 
My Mother the Car. It's not as bad as it should be.)
Seriously, people fall over themselves to explain that the Shatner/Nichols kiss wasn't the first interracial kiss on American TV...
And then they just move the goalposts. We're not talking about Culp and his wife, France Nuyen. We're not talking about (the still rather risky) hasty peck between Davis Jr. and Nancy Sinatra. We're not talking about British TV. We're not talking about Poitier and Hartmann in 
A Patch of Blue.
We're talking about 
the first, extended, black/white kiss on American TV. Something they made sure never to do on 
I, Spy or 
Mission: Impossible, two other hip, contemporary, Desilu productions.
For fuck's sake, why can't 
Trek get the win on this one?
