By insisting that its users declare that they "like" pages they want to follow, Facebook actually creates all kinds of potential headaches.
FORTUNE -- On Facebook I have "liked" both the conservative American Legislative Exchange Council and that group's arch-enemy, the liberal Center for Media and Democracy. Those two organizations loathe each other. I don't particularly like either of them, but I do follow news surrounding ALEC, and the only option Facebook offers for following ALEC's page, and the page of one of its chief critics, is the "like." You can truly hate something, but if you want to follow it on Facebook, you have to declare that you like it.
