One id dependant on the other. You can't be an individual without a more common thread holding others together, be it society or your class at school or the friends you keep. So, it's all very ying and yang in that respect.
In my opinion, it makes more sense to want everyone to have a common trait or characteristic, that way you know how not to be.
But, at the same time, if you and all your friends hate being like everyone else, then you're all basically the same and thus not unique. So, I guess that says something about being an outcast. Once you start hating everyone who doesn't like you,(because of the way you dress or talk or think) all you do is give them more fuel for their fire.
I love that commercial for Teen Titans where Raven is standing in a club and some dopey kid walks up to her and says something to the effect of "everyone sucks...you wanna go talk about it"...good stuff. And I don't even like Teen Titans
