[@Shoryu Magami] Data provides an argument for equality of all people, particularly in the ep where it comes up whether he's property or a person.  Do that with an actual human and you'll have people up in arms, not to mention everyone will have a preconceived notion, but talk about an android and suddenly people actually /think/ about the question, and what it means for the person being discussed (Data).  It's less about robots, and actually about /people/.  Robots having souls is a question other works handle.

My quibble with Romeo and Juliet (and I've seen productions of the play, as well as read the written script) is that its presented as this great and powerful love story, when really Juliet was barely more than a child, Romeo was like thirty and had just been dumped, they knew each other for a few weeks at best, and most of the people involved were idiots.  *shrug*  My opinion, and I see where it's viewed as a classic and so on, but there's loads of better stories.
