Kimophobia: fear of being a male ingenue
Seriously, the Kim speech on love is just conventional thinking. The truth of an idea is determined by the intensity of emotion it evokes. The true self is more important than anything. And, no matter where you are or what the situation is, you've got a career, even if you are sacrificing it for love.
The notion that anybody on Voyager is having a career is the really crazy part.
PS I'm not sure how I would have written Kim, except that I hope I wouldn't have written him as Voyager did: A token minority.
