Point taken, I just think that it's normally not good. I also think that maybe, for instance, libertarians and liberals have different conceptions of selfishness that lead the former to go 'yay, selfishness!' and the latter to go 'boo, selfishness!'. Are they talking about the same thing? Are we talking about the same thing? In my personal experience, selfishness has always been demanding half of the pie when fairness is one-third, leading to conflict and bad experiences that could have been avoided. We might just have different conceptions of selfishness.
