Hm. Well ninjas are pretty adept but they have their disadvantages.

Firstly, numbers. Ninjas have to train and train and train and train in order to get to the position of skill they have. Pirates on the other hand have little to no skill and thus, have much larger numbers.

Secondly, honor. Ninjas may be assassins but traditional ninjas still have a code of honor. Pirates don't. Pirates will cut your throat at the dinner table if you make a bad comment.

Thirdly, pirates cheat. Always. If you think you're in a fair fight with a pirate you're probably about to get a big surprise in the form of a hand cannon to the back by his buddy.

Pirates of the Caribbean. End of story. And besides everyone thinks pirates are better than ninjas. They're more popular and no one except trekkies think that ninjas are cool.

I'm going to make a few points to settle this debate once and for all and prove that pirates are better than ninjas and I'm going to be realistic about this: FIRST OFF: Pirates and Piracy have been around ALOT longer than ninjas. Piracy originated in 13th Century B.C. in the Mediterranean and Aegean Seas. Ninjas came about in 14th Century A.D Japan. SECOND: Pirates were incredibly brutal, vicious killers. They weren't frequently drunk as depicted in pop culture. In fact, pirates were rarely able to get their hands on beverages such as rum due to their life at sea. Raids and Pillages idn't come often. THIRD: A ninja's skills are greatly exaggerated. That fast as lightning stuff or whatever is absolute bullshit. They're not super human, they don't have "powers" that regular people do not. LASTLY: Pirates are real. Let me explain. We know pirates exist. They're active at this very moment. A ninja is an ideal. They're almost a myth in a kind of a way. You don't ever here of ninja attacks in the news. There are no secret ninjas cults that aren't made of geeks living in their mothers' basements. The point is: The Ninja is extinct and Piracy is alive and well, END OF STORY!

Pirates are smart. In real life they were clever problem solvers. If not, they wouldn't have had control over the Caribbean for the 250 or so years that they did. Also, they are vicious killers. The ninja would waste his time doing acrobatic moves and the pirate would take his gun out and shoot. I agree with PirateLord on everything especially the fact that a ninja's skills are highly exaggerated. Pirates are alive, ninjas are dead. Hoist the colours.

Pirates are unpredictable. With ninjas you're going to expect the unexpected. They are totally predictable.

pirates rule! it is said that pirates have formed the first democracy when a major decision is made all the pirates get together and vote on what to do next so all members of the crew had a say. this lead to the type of gov't we have today so thank you pirates!
