If it's not benign information, though (like political affiliation), it's worth asking oneself about the therapist's values. For example--and this is just an example— I would ask myself if could I see a therapist who supports someone who openly admitted to sexually assaulting women. For me, that's a deal breaker. For your situation with this therapist, maybe it's more of a discomfort and may depend on your own history. I also couldn't see a therapist who is homophobic, so if I found that out, I would leave. I think there are a lot of reasons to question whether or not a therapist is the right one for any particular person.
