Why do Yu Yu Hakusho fans think Yu Yu hakusho can beat up any anime?

THIS QUESTION IS ONLY FOR THE PEOPLE WHO ACTUALLY KNOW WHAT I'M TALKING ABOUT. Let me start. One piece vs Yu Yu hakusho. This is the most arguable. Now that it is 2011, Luffy is strong as hell. If you watch one piece, you know what i'm talking about. Don't get me wrong I luv Yu YU hakusho. I watched it twice. On to the next one. Yu Yu Hakusho vs Naruto. This is more on Naruto's side. His nine tailed fox killed the strongest member of the akatski (pain). I know there's a guy on Yu Yu hakusho that could stop naruto from using the nine tailed, which makes it difficult. Lets not forget the S rank demons. Okay, this next one is weird but just stay with me. Yu Yu Hakusho vs Death note. I asked this question. I got 20 answeres, and they all say Yu Yu Hakusho. I don't wont to burst you fanboy's bubble, but this is impossible. Even if they kill light. They can't kill a shinigami. He would just write all there names down. I didn't ask that last question because I hate Yu Yu Hakusho(which I don't). I just wanted to see if anybody would actually be dumb enough to think they would beat death note. The next question I asked. Yu Yu hakusho vs bleach. I know. That probaly got you pissed. I actually believe bleach would win. After Yu Yu hakusho beats ichigo's team, they still have to fight the soul reaper captains. When Yuske's team and the soul reapers are down. You still have the S rank demons. But, they still have the problem of Aizen and the espada's. People who watched both of theese shows and is actually caught up in the japeneese version of bleach. Know for a fact espada's are at least 2x more faster and stronger than S rank. Please don't so they aren't if you don't even know what your talking about. Last time I asked this question, People said espadas aren't and don't even know who Ichigo is. My last question, which made me ask this. You guys wont beilieve. Theese fanboys are soooo much on Yu Yu hakusho's dick that they said they could beat ................Wait for it.........DBZ. WTF. I don't even have to tell you how much DBZ will kick almost any anime's ***. NO offense. Just tell me why the **** do people think like this
