I still don’t see how the parents could encourage their daughter to make wise choices about medical treatment by facilitating - and presumably paying for - medical treatment they believe is counterproductive.
Parents are Christians, and believe the Bible, and what God says are abominations. Here is one scripture reference:
Deuteronomy 22:5 5A woman must not wear men’s clothing, nor a man wear women’s clothing, for the LORD your God detests anyone who does this.
Oh, I didn’t say paying for.
It was just my opinion that they could have had her stay with them because they love her, that they were there for her, that they didn’t agree with transitioning but they would love her. Then allow it, no paying for it, and keep her close, and slowly slip some words of alternative treatments or their deeply held beliefs, bit by bit, week by week, month by month. I believe to have the support IN GENERAL of the two people who love you the most could make a long term difference in her eventual healing or peace with her condition.
