People here have done considerable commenting on this already. But I'm happy to see that other media are picking up the story and spreading it farther abroad.
Yes, Savannah's testimony has been slowly spreading.
I see her testimony as a young girl speaking truth to power. She has a moral right to speak. She was born into the Mormon church, blessed, baptized, the whole nine yards. How painful must it be for her to say that there is no place for her in this church? That she will never be married in the temple? And (implied,) that if she does marry, her children would never be baptized into her faith?
I think that more marginalized Mormons need to speak out -- women, young people who don't want to go on a mission, minorities, the poor, and the LGBTQ. It's their church, too.
