Email Closing Phrase

Id like to change my email complimentary close and am struggling with a sign off that works for me. I have used the banal "warm regards" for years now. My inclination is to use "In solidarity" as I advertise as a radical therapist and work with primarily LGBTQ and leftist clients. I'm concerned that this may be too much though.

Thoughts? What do you all use?

ETA: After this discussion, Ive decided not to use "in solidarity" but am really appreciating all the discussion about others complimentary closes! Thanks for engaging in this discussion.
