You said,
“As they very well should. Opposing a psak in secular court (or choosing a secular court to arbitrate as opposed to beis din) is strictly against Jewish Law, as you very well know (assuming you are an Orthodox Jew). As such, a beis din is completely within its right, legally and morally and ethically, to use communal pressure to encourage someone to adhere to halacha. (And applying such pressure is completely within the secular law of the land.)”
Again I will repeat what I said above. If you do not see the Moral and Ethical problems with threatning to harm somebodys innocent children in order to get them to do something, I have nothing to say to you.
