Sounds like a really cute story. And there are a few similar titles, using real people rather than anthropomorphic animals, that have been out for years on this topic, including the famous Heather Has Two Mommies.

I wonder if what makes this title so offensive to some people is the fact that they are penguins… or two *daddies?*

And hmm…maybe scifi dad is really on to something w/ his post about discrimination against “fatherly” men.
