Like many other posters, it depends on what the disagreement is about and how they handle it. I have never seen a Freudian T, I don't think I would like that, so I probably won't ever seek that out.

Religious differences are ok as long as they are not pushy about it. T3 and I think differently, but she asks what I believe about things and is respectful about it. She will sometimes suggest that I tap into my faith for a specific purpose; eg can you think of an example of someone who practiced forgiveness in your faith tradition?

If I like a T, I would probably try to be clear about what I want/need in terms of things that we disagree about and see what happened.
