User blog:Eustass el kid/New Nakama Hate?

I've been noticing a lot of people don't like the idea of anyone else joining the Strawhats. I've seen it on other sites, on one piece reviews, and even here. Why though? Is it because people think that the strawhats have enough members or are you guys/gals just annoyed because every new character who pops up is a new "candidate" for the strawhats lol. Give me your feedback everyone it'd be much appreciated.
