Excellent question wizzstick. Shame about the non-answer.
I wonder if others know the facts surrounding the Mormon church abandoning their racist teachings? As I understand it until 1978 they taught that people are born black as a punishment for failings during their prehuman existence and they were not allowed to join the Mormon priesthood.
Did that racist teaching actually become illegal or did they abandon it because of social pressure? If a church wanted to continue teaching racist beliefs would that be allowed?
I am curious because I agree with wizzsrtick these situations are comparable.
My guess is that the Mormon church changed because of social pressure rather than actually be ruled illegal. I think a similar dynamic will play out with Watchtower bigotry. It won't be made illegal but it will become so socially unacceptable that they have to change.
The Watchtower says "people can change".
Well I say "bigots can change!"
