I personally think it would be wrong for a therapist to deliberately try to make a client angry. I know there is this famous 'Gloria' film on YouTube where the Gestalt therapist is deliberately rude and then explains that he is trying to make her angry. I personally think that's wrong and also inexcusable, and I have the impression that therapists nowadays wouldn't try to be deliberately horrible or make the client angry on purpose. Or at the very least, they know they are not supposed to behave that way and they don't try to say that it is therapeutic!
That's what I think, but of course I'm not a therapist...
I think in your position I would plan to use my next session talking about this issue. It seems like it is something important to you, and I imagine if you try to let it go it might fester and be disruptive for your therapy. I think if you bring by it up you will have more of an idea about where T stands with this and whether T can appreciate how important it is for you, once you have explained.
