For me I would like my therapist to have basic reasoning and critical thinking capabilities, so that would be a no on therapists into homeopathy ¯\_(ツ)_/¯
If a T has different beliefs about religion or ghosts or something else that's not part of the natural world and cannot be proved or disproved then that's fine. But there's plenty of evidence that homeopathy is BS.

If switching Ts isn't an option, I think if it were me I might almost prefer not to address it and instead just try to ignore or forget about it. I don't think a conversation about it would help, and I'd just end up more frustrated.
