The rest of the movie effectively eliminates moments that might mean something by depictng every teenage boy, without exception, as cruel, violent, vicious, and seething with unexplained anti-Daniel hate. Every word boys say is a boast, an insult, or a threat. They wear skeleton costumes to the Halloween party to demonstrate their evil, and their karate uniforms are black to contrast with Daniel's Luke Skywalker white. In contrast, every girl Daniel encounters is an angel, nurturing, supportive, tolerant, and kind. This is heterosexism run rampant, proof positive that same-sex love, friendship, or even polite co-existence is utterly impossible. Love, friendship, and even the freedom to walk across the cafeteria without harassment can occur only in the company of girls.
The DVD box shows them face to face, mouth to mouth, gazing at each other as if moving in for a kiss. But Miyagi is elderly and Asian, movie code for "asexual." And, so no one worries that a stray look might mean something, Miyagi is shown drinking to the memory of his dead wife, thus "proving" that he is heterosexual.
Usually he was thrown into worlds so heavily polarized into vicious boys and nice girls that same-sex intimacy seemed absurd. In Karate Kid II (1986), both Daniel and Mr. Miyagi both fight cruel, violent boys and get girls.
In Distant Thunder (1988), en route to a reunion with his elderly father, Ralph and a kind, loving girl are kidnapped by her cruel, violent boyfriend (Reb Brown).
Not until My Cousin Vinny (1992) did Ralph bond with a boy, a fellow college student waylaid by a murder charge in Alabama. By that time, an entire genre of Ninja kids had evoked their own worlds of cruel, violent boys and kind, loving girls, rejecting the possibility of same-sex love over and over.
