I do think it's a question of semantics. I would translate you into a person who've mastered negative feelings and can transform them into indifference (when it comes to people), which is good. There are plenty of people in the world who won't acknowledge "negative" feelings at all, and very often this "trait" becomes very hurtful to themselves and more importantly to their surroundings.

Also, I do believe that anger, as an initial feeling, transformable into other feelings, is needed in moderate doses in order to create change.
