To get governments to stop funding any group that demands its members shun individuals you have to change the law. That means legislation first.
If there was such a law that would mean no group could force a parent to throw their child out of the house because they don’t want to go to meetings. Or stop talking to their 10yr old child who made a mistake after being baptized. No child or adult with serious mental health problems who breaks a rule would be ostracized until they obey and even then they have to endure months or years of ostracism. No parent would be cast out and then shunned for giving their child needed medical attention. No spouse would be thrown out and deprived contact with their children because they are a danger to their spirituality.
If you think “Sticks and stones will break my bones but names will never hurt me” is true, then you have not had to endure even one of the above.
Constant abandonment and neglect is traumatic. It is a trauma that exists for a lifetime.
I grew up in a verbally and physically abusive home. Every beating had an end. You knew it would only last a while before your attacker walked away.
But the words, the hatred, the anger, the screaming stayed with you much longer. It continues to live in your head and heart for years.
If you think that isn’t violent, then I assure you that the emotional and psychological impact is violent enough that many people, like my sister, commit suicide to stop the words in their heads.
