Umberto, it's great to have you back I love your posts. Well done, you are so brave. There are great suggestions on here already, re background checks, mandatory reporting, etc. also no known abuser should EVER be allowed d2d or privileges.
I really don't see it as unreasonable to look at their tax exempt status considering their lack of protection for victims, but protection of the perpetrators and their disfellowshipping and shunning policies, particularly in families. We are talking about an organisation that in some cases, has ignored abuse victims and left them and other children in danger of further abuse, protected and even promoted the abuser, refused to report to the authorities, and then when the child grows up and understandably leaves the religion, subjected such child to institutional shunning even from family.
Not to mention general shunning, discouragement of higher education, disdain for non witnesses, lack of genuine charitable works etc. etc.
How can they justify charitable Status?
one more suggestion, a national database online where any householder can register their desire not to be called on by witnesses
