re: #17 EPR-radar
For something to be banned from public schools on separation of church and state grounds, I think the activity to be banned has to be some form of religious indoctrination or training.
It is difficult to see how a yoga class that is only focused on the physical movements would qualify.
What is next —- ban the idea of the golden rule from classroom discussion because it is embraced by several religious traditions?
IMO, a conservative legal foundation would file a lawsuit like this expecting to lose, as a useful way to discredit church/state separation in public opinion.
Bug zackly why they should & will likely win this case.
