Everyone has judgements and opinions. There's nothing wrong with that. If the judgement interferes with the work, then there is something very wrong with that. I know that if I am working with someone that I have a judgement about, I ask myself why and just work through it so that it doesn't get in the way of the therapy. I really think the whole point is that a therapist doesn't have to AGREE with what a patient does, but he/she does have a responsibility to ACCEPT whatever it is.
