I think the "first interracial kiss" thing between Kirk and Uhura is oversold, for a variety of reasons. But Ricardo Montalban clearly kisses Marla McGivers in "Space Seed," long before the Kirk and Uhura moment. Montalban was Mexican American, and while many Latino/Hispanics consider themselves white, not all do. In addition, he's supposed to be playing an Asian character. Is this moment really the first interracial kiss on Star Trek? Or do we fall into the tired idea that race is only Black and White?
