BYU's LGBT association which I co-founded, USGA, recently posted The History of BYU and LGBTQ Issues to their blog. I reached out today to one of the authors with the below, providing additional context on that change.
I just finished your/Hayden/Elijah's excellent article, The History of BYU and LGBTQ Issues! Would you be interested in additional context behind the Feb 2011 honor code change? You may wish to add a line or two to the article, or perhaps publish a dedicated article on the subject. I'm one of the original founders of USGA, helped with the BYU LGBT history Wikipedia article, and have some insight into that change.
The emeritus general authority contacted me again, this time saying "There is enough concern about your book that the President of the University, your priesthood leaders, and General Authorities are worried about it and my counsel remains even stronger that you need to put it aside and let anyone know to whom you have sent it that you are going to let the Church handle the issue as its leaders feel inspired to do. In no way do you want to end up in a disciplinary situation." A BYU stake president pulled me aside to condemn my book and actions and warn me that Satan was "separating me from the herd" so he could take me down. An influential BYU professor wrote "you are not free to dictate what the reaction of Church leaders will be towards it. I would suspect (having interfaced with the General Authorities for many years) that they are not going to take kindly to your book which will, because it is logical and well-written—lead many people away from the Church’s mainstream teaching. If I were to counsel you, I would say to put the manuscript away until the Church changes its stance." Two law school deans confronted me about the draft and reminded me they have no power over the Honor Code Office (HCO).
To keep a long story short, I nevertheless persisted in publishing the book the next month (December 2010), and sold copies to several libraries and the BYU Bookstore (where it sold out). QSaltLake featured me on the cover of their 3 Feb 2011 edition, including articles about (1) my book and (2) the Feb 2011 honor code change. My book included a chapter entitled "A Moral Case for LDS same-sex marriage" that explored moral arguments for and against same-sex marriage in the context of a thought experiment.
Hope that helps,
