The point of debate is to test ideas by argument and logic and strengthen the strong ones and reject the weak ones. If you just say "Here are our thoughts," then the "what about robust debate" rationale doesn't hold up, and we can get to the direct question of whether James' worldview is moral or immoral, because the people taking the "advice" are going to have to pick either perspective A or perspective B.

And if you're going to pick one in the end, why not get everyone from that worldview? There are lots of Roman Catholic theologians, for instance, that they could have included. I don't personally agree with them either, but they absolutely have a rich history of thinking about ethics, and they mostly also don't believe in trans people. Why leave James to fend for herself?
