This completely went over my head as a kid. I'm so glad it did.
The bad guys from "The Little Mermaid," "Transformers," and "The Gummi Bears" all have one thing in common. And when he points it out, it's hilarious and kind of infuriating at the same time.

What he's talking about here is a classic example of a microaggression, which is defined by Wikipedia as a "social exchange in which a member of a dominant culture says or does something, often accidentally, and without intended malice, that belittles and alienates a member of a marginalized group." Here are a couple of examples of how microaggressions play out to real people in the real world. Bottom line: They really suck.
