I don't know if it's necessarily wrong for the therapist to treat (not so much regard) the client as an opponent.

Current T has pointed out a couple of times that I seem to find it incredibly frustrating that she doesn't argue with me. Much to my further frustration, she's right.

Her tactic when I get angry is to try (in ways that I think are utterly feeble) a few times to get me to see past it and when that fails to just leave me alone until I am somewhat calmer and willing to engage again.

Until very recently, I took her tactic of leaving me be (when I'm angry) as disguised hostility -- viewing me secretly as an opponent but not actually overtly treating me as such -- but then when I saw that she's gone out of her way to accommodate me when I calmed down (and even after I'd told her some truly horrid and vicious things), I realized that it was in part her seeing through my attempts to get her to tangle with me and also likely in part, her general non-confrontational style.

In all honesty, I would greatly prefer if she could display overt hostility and then we could have a knockdown dragout fight to clear the air and move on. Because, else, here I am stuck with a lot of rage that I don't quite know what to do with.

To sum up, I guess the answer is that it depends -- different clients may need different things and then the T may or may not think that it's appropriate to engage certain clients in certain ways.
