Pirates or Ninjas?

(Nick and Tom are my two friends that live on a random website found by typing Harry Potter and Ninja into the Google. This is a conversation between them, which I tried to join, but they're pretty exclusive so I only got a few words in edgewise.)

Nick: Do you think Harry Potter is a Ninja or a Pirate?
Tom: I think Harry Potter is definitely a Ninja
Tom: it's the cloak of invisibility
Nick: Really?
Tom: but Ron Weasley is WAY pirate
Nick: I would have said the relentless good feeling made Harry a pirate.
Tom: I'm going to categorise EVERYONE into categories of ninja and pirate from now on:
Tom: Margaret Thatcher - pirate
Tom: Bill Gates - pirate
Tom: Steve Jobs - ninja
Melissa: Jessica MacMurray Blaine - ninja
Melissa: Karen Stapleton- ninja
Melissa: all the MICE - ninjas
Melissa: Frank MacMurray - ninja
Nick: And Ninjas are, of course, creatures of the night, subversive, rejecting the male authority...
Tom: exactly
Tom: much like...
Tom: Britney Spears
Tom: - ninja
Nick: Subtle rather than confrontational, weaker in a head-on confrontation...
Tom: actually no. she's a pirate
Melissa: I agree
Melissa: Barak Obama - ninja
Melissa: Sarah Palin - pirate
Melissa: Voldemort - pirate
Melissa: I will now be categorizing everyone as a ninja or pirate. It's addictive, much like Kanye West. He's definitely a ninja too.

Ninjas read Harry Potter too:

Let HP get you through the day my friend.
