Anyone know if Suikoden III is an example of this? IIRC the main protagonist knew about... his origin and felt like it made him a lesser person.

I'm confused. Sex Is Evil And I Am Horny is supposed to be an Internalized Categorism trope, but it's also an example of the "not-so-internalized version" of internalized paraphobia?

Yay, finally got around to reinstalling photoshop. I just had to include a page illustration from that scene in X-Men: The Last Stand. IMHO, that movie in general and that scene in particular captures the concept of categorism better then any other work I have seen - especially since the mutants have so very little in common. Characters keep discussing the issue of "the mutants", as if mutantship was a coherent phenomenon. The fact that Angel has wings to fly with doesn't make him a threat to anyone, but he is still viewed by himself and others as if he was the same thing as the very scary Phoenix that was showed in the previous scene.
