>and thinks "human" is a proper noun.
Not surprising; I blame leakage from other media sources. I mean, just for example, if we're going by how the word is used in both the in and out of game literature, "Prothean" is apparently a proper noun; it's almost always capitalized, at least.
I see "Klingon" and "Romulan" capitalized a lot in Star Trek sources as well, indicating proper noun status when it isn't being used as one.
For that matter, "Gamilon" is capitalized more than once by the production team here in UF, even in contexts where it clearly isn't being used as a proper noun. I can find a couple examples of that just in a cursory check of S1M1.
