You think Kirk kissing Uhura wasn't making a point?
Not really. Everyone knew Kirk was randy as hell.
Ah, no, Wayne. The entire point of Uhura, Sulu, Scott, Chekov and especially Spock was to break the entire doctrine of fear of all white all the time and drive home the message that all people of every race (or planet) are equal, and can live together in peace and harmony toward a higher end than mere acquisition of wealth or power.
Yes, the Kirk/Uhura kiss was aimed straight at testing and breaking the racial boundary on TV, but Kirk didn't kiss her because he was "randy," he kissed her because he was being forced to by the people there where he was at.
