"It repeated an early Rabbinic view that Adam was intersex before being separated into male and female."

Hm. Ok. Interesting, in that "Adam" was literally named prior to the separation event, and the name is not sexually ambiguous. (The early Rabbis speculated on a lot of things, even the now-heretical notion (to Jews and Muslims) that the Ancient of Days mentioned in Daniel was a suggestion that the Godhead was not quite as unitarian as traditionally believed. I always found that interesting; not sure if they burned the rabbi at the stake or not. :-) )

"I agree concerning the approach of trans occurrence within the realm of feminine names applied to God."

Sure. It's always seemed to be that the locking the creator-god into the male role was for literary convenience rather than necessity; it stands to logical reason that God is "above" sexual definition; the Quran is clear that He is a being unlike any other, and that is an idea which is not in conflict with Jewish or Christian theology.

So, when it comes to the reality of the "trans" state, though, pointing out the fact that feminine names were applied to God is a lot simpler to explain than the idea of an intersexed Adam, and a lot less emotionally impactful to the believer. In short, it's an easier sell.

As you're probably aware, both Sunni and Shia Islam (which is about 90% of Islam) acknowledged the reality of the trans condition by fatwa from the most respected scholars of each sect about thirty years ago. So, the existence of transgenderism, to Islam, is not in doubt; Gen 1:27/5:2 remain authoritative and are are not considered to be in conflict.
