Good to hear. I will be the first to advocate for freedom of speech and religion and adherence to the US constitution, but whenever someone says that you can't have both, ie you can't legally discourage shunning and not be on a slippery slope I disagree.
You of course can't force individuals not to shun (nor would you want to) but you CAN decide to not grant privileges to religious entities who require such behavior lest the persons themselves be shunned.
Just like consequences for criminal threats isn't a violation of free speech, and just like not allowing a weapon for someone with a history of criminal violence isn't a violation of the right to defend oneself, so too this wouldn't be a violation of religious freedom. In fact it would be a defense of it seeing as millions aren't free to worship or not worship the way they choose, being held hostage based on explicit organizational instructions.
