But.....Roger isn't a bear.
I don't know much about the bear scene or bear culture as it were, but just based on the film's definition, Roger is not a bear. Tyler reveals that he likes bears and then immediately falls for a man whose only resemblance to a "bear" is some facial hair. I think the movie kind of cops out when they have these two end up together without explaining that perhaps it wasn't neccesarily a bear that Tyler was looking for. And I don't even think that Roger was all that likeable anyway, but that's another discussion.
Sister, when I've raised hell, you'll know it!
