Japanese court gave a decision that community shunning was illegal.
This was a court decision without any religous contexts. But Judge said if the shunning was used as blackmail, it is illegal.
In United States, the community shunning is OK if its because of religious belief.
But if it is in school, is it OK??
Let's take an example for arguments, Most of students in a class room are Jehovah's Witnesses.
One day, one of witness students is disfellowshipped in local congregation.
Other witness students begin to shun him and geet him no more at school.
A teacher noticed this, but students said "Well, this is because of our religion. So teacher, you don't have a right to stop our custom!"
Do you think it's OK in this case?
I think you can not control what they believe, but what they behave must be regurated by secular rule.
