It's been shown, and admitted to by LDS church leaders, that their past prophets from the first to Kimball were wrong about not ordaining black men to their priesthood.
Interestingly, there is more reference in their scripture about certain races or people being denied the priesthood (in the book of Abraham, Book of Mormon) than there is about denying women the priesthood.
The LDS church's late 2013 essay on Race and the Priesthood tried to exempt Joseph Smith from the lineage of racist prophets by claiming, "there is no evidence that any black men were denied the priesthood during Joseph Smith’s lifetime."
It sounds to me as if the LDS church is proud of those leaders who were ahead of their time in ordaining minority males to the priesthood when they say the world view was against it.
Why wouldn't they say the same thing about Joseph Smith ordaining women? I won't expound on the events surrounding the history of Joseph Smith ordaining women, but D. Michael Quinn showed plenty on it. There are many saying the LDS church is wrong to discriminate: You should have a look at the Ordainwomen website to get more information.
What I want to challenge here is, why aren't there more active men who stand up and step forward for women, and Ordain Women Now? Your prophet is a sexist, so stand up and go forward by ordaining Kate Kelly or any other Mormon woman who asks to be ordained. Don't be ashamed of your small support for females. Be a large man and stand tall for women. Lay your hands on them, give them the priesthood and report it to the world.
If and when the LDS church leaders come after you with a disciplinary court, stand tall and lead. Let the chips fall where they may. You'll make history when the future church proclaims that it doesn't know how or when the ban on women started but is against all forms of sexism, past, present or future. And you can be listed among those brave LDS saints that stood for priesthood equality.
Ordain Women Now doesn't have to be a movement waiting for change. Just ordain women and make the change immediately.
Sit high, look forward to a bright, if uncertain future.
