Re: ST VI:TUC Out of character for McCoy?
Never before in Trek history did someone react that way to a Vulcan mind meld, so agaiin it was hard not to miss Nicholas Meyer/Leonard Nimoy's rape allegory.
Unless you're with Writers Guild West and/or have seen all versions of the scripts, I don't think you can necessarily accuse only two specific writers. The writing credits were determined by the Guild through arbitration; Meyer shared screenwriting credit with Denny Martin Flinn, and Nimoy shared story credit with Lawrence Konner and Mark Rosenthal.
