It's really important to find a therapist who can understand your situation, or at the very least will genuinely try to. If they get defensive about being challenged, or questioned, or they judge your legitimate viewpoints, I would say, find a better one who is more receptive and open. I wish I had known such things when I went to therapy, and I really wish, I had prepared and asked more questions about the therapist. Therapy is for you, it's their job to give you an adequate service for your needs. You shouldn't have to feel guilty for wanting to leave if you need to. From personal experience, there are a lot of really mediocre ones, so please find the right one for you.
