IF the issue is the cross being on federal land...then what could be the objection to transferring the land to a non government owner? Federal property is routinely sold and transferred.
This surely sounds like judicial hostility to religion, and a spiteful judge for sure...similar to the judges' personal animus against Terry Schindler's family.
Has the self-same atheist vet sued to have crosses removed from Arlington and other Veteran's cemeteries? Also maintained at federal/state expense.
