For those of you that think Ninja's are better than Pirates, there are a few things to consider.
1. Neither have magic. No gay animes will change that.
2. Ninjas train for many years to become a Ninja. Pirates become Pirates they day they want to be.
3. Pirates have a boat. Ninja's can't kill them when they are in the middle of an ocean!
4. There are Ninja-like Pirates, but no Pirate-like Ninjas.
5. Pirates are still around today. Ninjas, not so much (I understand exceptions).
