I'm not going to get into whether same-sex relationships are, or are not approved by God. But it is explicitly against the "Commandments of God" as defined by the leadership of the LDS Church, and is treated as a serious sin in magnitude next to the shedding of innocent blood. Most of us disagree with the absolute authority of Church leadership, in dictating how God feels about this or that. But, in assessing the actions of both the girl, and the SP counselor, it's important to keep this in mind.
You're right, DJ. She didn't explicitly advocate others to follow suit. At most, it was implicit advocation, encouraging by example. "This is who I am, this is what I'm going to do, and I have God's approval. I will be happier this way." It is vindicating the violation of a commandment, and open opposition to Church authority (whether you agree with it or not).
