I wouldn't sit in an enclosed space with anyone who wouldn't tell me their vaccination status. Depending on the circumstances, if they were unvaccinated I might stay, but I don't know. I do know that I wouldn't continue to see a therapist who refused to tell me if they were vaccinated or not. It's not like you're asking for their health history and it's directly relevant to my health. I would tell them why I refused to see them at that point also.

I also wouldn't continue to see a therapist who I thought was a closet -phobe of any sort if I fell into that particular demographic. Or just in general. I don't see how anyone with those kind of prejudices could be an effective therapist.
