I think it might help to think about how anyone you knew in this context might react. People know everyone googles or looks others up on Facebook, but don't necessarily tell each other about. Facebook especially is a rabbit hole- after a couple of clicks you can get pretty deep into someone's life. Therapists who don't understand this make too big of a deal out of something that's really natural. Before the internet knowing this information would have been a concern because it would have taken some serious effort to find it. Now it's so easy and free that it's harder to keep this stuff private. I think a social media savvy T understands the difference and wouldn't be so concerned that you found the information. They may be more curious about why you want them to know you found it. That's the first thing I'd think of, anyway. As a T, they have no right to tell a client or anyone else whether they can or can't google them or look them up on Facebook. For some reason, some of them think they have this authority but the reality is they don't.
