I want those common-usage connotations brought in because I want to eradicate the taboo around those common-usage connotations, I guess. I think that people are vilified for being selfish in lots of situations where being selfish is a good thing, at least from that person's perspective. I don't think that people should ever get mad at defectors in Prisoner's Dilemmas, for example, and I think that saying that all of morality is selfish is a good way to fix this kind of problem.
