If you force two people to kiss, this is not rape. It's "forcing two people to kiss." There was no sex involved, it was designed to humiliate.
"Rape" has long been identified as being more about power and control than sexual gratification. In fact, that was the exact purpose and motivation for forcing Kirk and Uhura to kiss. Also rape is not limited to just coitus but rather any intimate contact (such as kissing or petting).
Would it be more palatable to say, "sexual assault?" Is it a mere matter of semantics? Wouldn't that still disqualify it from praise?
Their minds were not controlled, so it wasn't "mind rape" either. It was a violation of their will, yes, but rape? Nope.
Did Kirk and Uhura kiss of their own free will and under their own power and control? Free of any outside power or influence? The answer is, unequivocally, no.
They did not kiss by choice. So how can one rationally, credibly say it was anything other than a rape or sexual assault?
Following that, how can a group choose to elevate it for glorification?
