First and immediate thought that comes to mind is "If the group is going to get itself deeper into trouble, consider leaving the group." Because you referenced Isaac Bonewits, I'm going to guess that your problem is metaphysical, and if the group is going to continue messing with stuff that it shouldn't, getting yourself away from Ground Zero and separate yourself energetically from them might be a place to consider starting. Then work on shielding yourself and figuring out how to mitigate your contributions to the issue.
Just my $0.02.
