There are definitions that are adjectives for those words, yes. However, there are also definitions that are nouns as well:

http://dictionary.reference.com/search?q=dominant

http://dictionary.reference.com/search?q=submissive

Unfortunately, the dictionary.com definition of submissive does not include the same reference resource as it does for the word dominant, so that particular definition is not attributed to a person.

Kind of short-sighted in my opinion. Maybe I'll write them a note.

You would be correct in that assumption. In fact, there was a discussion recently that was started by a member here that also thought BDSM was just an activity. You can view that topic here. I think it might offer you some insight.
