In "Troq," we are introduced to the spacefaring hero Val-Yor who really hates Tamaraneans, the alien warrior race that Starfire belongs to. Now, upon meeting Starfire, he doesn't set a wooden mustard bottle on fire on her lawn or anything, but he makes it clear he sees her as inferior and untrustworthy, and continues to refer to her as "Troq," meaning "nothing," as in she is nothing to him. The question is ... WHY IN BATMAN'S HOLY NAME DOES HE THINK THAT?!
Omitting the fact that Starfire is as pure-hearted as a newborn puppy, she is also considerably more powerful than Val-Yor-Tamaranean-Mama-Is-So-Fat. Val-Yor is super strong, can fly, and has a degree of invulnerability, but Starfire has all that plus being able to breathe in space, manipulate cosmic energies, and possessing quasi-immortality. And when someone as amazing as that can still end up the victim of spacism, it really makes you realize that prejudice doesn't need a valid reason to exist. It's just a shitty thing that shitty people do sometimes because they are shitty, and you should never let yourself internalize all that nonsensical hate, like Starfire almost did.
Throughout the episode, Starfire risks her life to show that she is useful and good until finally standing up to Val-Yor, but in the end, the best that he could do is admit that she was one of the good Tamaraneans because, as the episode says, some people's minds just cannot be changed. That is a very bleak but very real, no-bullshit message about the irrational nature of racism, delivered via a Jay Leno-lookalike covered in silver.
