I'm bored with your defamation already. It has come down to exclusivity of position based on meaningful differences and practical role differentiation.
The differences are more mythical than meaningful, and the role differentiation is programmed, not innate.
It is just a matter of fact that women have babies and breasts to feed them, nesting hormones, and multitasking brains, which suits them for fulfilling the role of raising the children.
Only 2 out of 4. There is no hormone in women not present in men, nor vice-versa. There is no particular advantage to multi-tasking in parenting, and the varience in multi-tasking ability outstrips the mean difference anyhow, to the mean difference is irrelevant.
I guess we could pretend men take on the provider role as a matter of default,
Those so programmed by culture, sure.
I don't know the answer to "Why is needed to exclude women from the bishopric or men from the relief society?" Maybe men have exclusivity in priesthood/and position of Bishop because women have exclusivity in having babies. It could be considered a matter of practicality since babies are a lot of work.
That doesn't explain why single, infertile, or menopausal women are also denied the position.
Maybe it has to do with the same reason men and women have different restroom facilities,
That's because men are culturally considered vicious predators that woman have to be protected from.
or why the Utah Jazz doesn't have women on their team.
Certainly, when you look for the top 0.00001% of the most athletic people in the world, very few women will be on that list.
Isn't it telling that the exclusivity goes both ways?
Did you know the Jazz once drafted a woman player? If there was a woman who could play on this level, shewould b in the NBA.
Why is it needed for women to be bishops and men to be relief society leaders just for the sake of some worthless need for a sense of universal fairness or equality?
It isn't necessary, obviously, sice it doesn't happen today. The question would be why you want to keep otherwise capable people out of the position based solely on gender, absent necessity.
Role differentiation, for innate or practical reasons doesn't mean inequality when they both are valued, needed, and get one to the same outcome.
Except here the innate reasons and pratical reasons are mythical, not actual.
