I'm not sure I understand. If you mean that you use anger to further some other response within yourself (ie. anger as motivation), then I suppose that would be an exception.
In the context of a debate or discussion, I'm inclined to agree with Jaguar. We see many of the same mannerisms from anger exhibited in passion, so it's only natural that they be somewhat confusing. Passion however, doesn't always cloud judgment and mental facilities like anger generally does.
