That can be a tough dilemma. I try to stay true to my values and end up with similar conflicts in different settings.

Although a therapist's political orientation may not impact her ability to do therapy, you have said that it would impact you as the client.

If her values conflict with your values, perhaps you can turn it into a learning experience to make the best of the situation. Your feelings about this could be something to work through in the therapy itself. Why are such values important to you? I think it is good that you have a solid self concept about your values. Perhaps talking about it could lead to enhanced self confidence in a sense that it may reinforce valuing and believing in yourself.
