Well done.  An important addition to understanding of not just transgender people, but for others who are part of the LGBTQI community.  

This struck me:  " ...recognizing their intent to live as the person they believe God created them to be, and refraining from judgments that might exacerbate struggles with gender identity."  and "  ... hostility and condemnation arise when we focus too narrowly on applying specific moral teachings to the situation and lose sight of the overall good of the person in need of support."  

I think what we lose sight of is not just the "overall good of the person" but the overall good person.  While we also need to help those "in need of support", we also need to just be open to those who no longer need our "support", are no longer struggling, but who have found the place where they do feel whole, and just love them, be open to their being part of our community.  Gay or lesbian marriage and trans people who have gone as far in their transition need go.
