Incivility is against the guidelines. Civil arguments and debate are fine. Normally I'd be happy to discuss the nuances of aggression and passive aggression, but the tone of this conversation has become overly hostile and I don't want to participate any more.

I disagree with you as to what passive aggression means, in that you have a narrow view and I have a broad view, but there's likely many mental health professionals who actively rely on the DSM in their work that would agree with you. I will certainly keep that in mind when I use the term in the future, so thanks for pointing it out.
