I am not in DBT, but I find your post incredibly judgmental.
When I read your message, it comes across as "emotions are wrong, so, since you think with your emotions, you necessarily think wrong about the situation".
The problem is not what you say, but how you say it.
Good advice don't need patronizing people.

@ScarletPimpernel It's ok to feel what you feel.
Whatever the why and the how, perhaps your therapist is not the right match for you. Therapists are not god, no matter their diploma.
If you feel strongly about the issue, you have the right to bring it up with your T. A therapist is paid to give you a service, the same way a gardener is paid to take care of gardens.
Even if the county pays for your therapist, it's still money paid to give you therapy. Therapy paid by the county does not mean that you have to put up with unhelpful therapy, exactly like you don't have to put up with an unhelpful gardener.
If you want, you can write what you have to say and bring it to the next session. You can say "I've been reading X, Y, Z (book titles and authors). However, in therapy, we do A, B, C (specific actions/advice/examples etc... by therapist) contrary to books X,Y, Z say. I am concerned that A, B, C don't help me for reaching M,N, O (your goals). What is your position ?".
Then, you see how T responds before you take any decision.
