In images, references, and stories, if there's a single parent and a daughter, that parent is always the mother.
If an adult male is seen with a little girl, there's a certain negativity to it; he is seen as distant, or unrelated, or disconnected. Or, it's used in a "fish out of water" sense, as the years of Full House and My Two Dads reruns have shown us.
The idea of the single father with a daughter is not a common image in our society, and I'm not sure if that makes it more difficult for me, or more special in it's uniqueness. I can understand why minorities become so emotional over the lack of representation in the media; as a minority by lifestyle, I lack of positive representation of single fatherhood to justify me to society at large.
