>if it can be detached from ego it can be transformed to a positive "wisdom".

I doubt it can be detached from the ego in anyone but the most advanced practitioners, if at all.

Anger creates a cognitive bias and narrows your attention to the object of threat. It distorts your perceptions.

I think the best way to handle anger is to acknowledge it and consciously try to let it go. Even the strongest anger will dissipate this way, because in order for anger to persist it has to be maintained by rumination on the object of the anger.

You're right, if you don't give the emotion any energy it will not persist very long, simple but hard.
