You refuse to answer my two simple questions.
You've asked the wrong questions. I've answered by giving you the question you should have asked and whose answer will solve your little conundrum.
We copyright our own stuff so you can't present it as being official.
"You" being all those who are not the prophets and apostles, correct. Only they can establish doctrine for the Church.
Kinda funny to copyright stuff, post it on your website, teach it from an official location/pulpit and then say: that's not doctrine.
I've not seen that happen. BYU is not an official pulpit. In fact, official locations and official pulpits don't exist in any doctrinal sense. If what's spoken from a location/pulpit gets published by the Church as opposed to merely being IRI stamped, then it becomes doctrine.
