How to I protect the witches in my area?

This feels so weird to type, but I’ve stumbled onto a hidden group of “Witches for 🍊” in my area. They’re doing the Hexenbrut (witches dance) and actively hosting events and such, and doing so at a business owned by a 🍊 supporter and when I click on the profiles of some of these witches, their views are also clearly displayed on background photos and posts.

Last year, I found myself as moderator of a smaller local witch group only to learn that my admin was a slur spewing highly phobic bigot, I immediately left the group and blocked her. But that left many witches in the group unprotected, but I’m thankful it’s no longer an active group.

Do I warn people away from joining these groups? Should I consult other admin of my state’s groups for council? I’m seeking advice from those willing to give.
