Aliasing rage → angry

Close enough?
Couple of potential problems with this: rage is tagged for other things once in a blue moon. There was at least one post of a character named 'Rage'.

Also, perhaps we do want to differentiate between different levels of anger? If so, this should be implicated instead. But what counts as rage as opposed to mere 'anger' seems a bit subjective to me.
