You were right the first time. While there are certainly worse philosophies than objectivism, a philosophy that holds self-interest as a (perhaps the) key ethical tenet has the evil built in.
PLEASE tell us exactly what is this "evil" that's "built in" to Objectivism!
Always bugs me when people state opinions as dogmatic fact.
Self interest is not only the key ethical tenet for Objectivism, it is the key ethical tenet for life. "The only thing wrong is you called it evil", Franscisco said. Which is why altruism is anti-life, it violates the rules of life.
Someday, we'll be rid of you people and will be able to live as men, instead of as brainwashed slaves.
