Its just ignorant assholes on a power trip playing god games and trying to emulate 2000 year old social morals of the ancient Israelites.
A complacently stupid thing to try and do in this day and age but there you have it.
Sorry you had to go through with such personal abuse by your ex-husband and the Great and Benevolent Asshole JWS,
but these things happen within organized religion and it happens a lot within many other religions as well.
