Judy Grasso isn't much of a Christian to use as any sort of example of it being ok. You can look at commandment number 1 to see the clear answer here. You shall have no other gods before me.
The kids parents should sue the living heck out of the schools for violating there parental rights to teach religion as they see fit to their children and not have the school or government interfering in such matters. They should also go after the teachers involved and principles and anyone who approved the program as an individual in court for abuse of authority I am sure these kids did not feel they had the right to say no. It is time as Christians we put our collective foot down and squash this anti-Christian movement in this country. Most our laws and 80% of the populace is Christian why are we pandering to the few?
