Like any trauma, some may fade with time and professional assistance, and some will be permanently incapacitating. But you are unequivocally stating that emotional trauma is permanent. I disagree, as does my psychologist bride.
Not to put you on the spot, but can you cite a source for your unique claim? I highly doubt any mental health professional would make such a sweeping claim without the qualifiers that I suggested, and you are bracing against.
Hyperbole is not straw. And yes, you are using the terms consistently with the literature. What I'm saying is that the literature is using them wrongly, and trying to slide some new starting assumptions in there. Some of us object to word games, at least on serious topics.
A newborn is not assigned male or female. It is male or female (sex ID). Their gender, whatever that may be, is not self identified yet, as a newborn has no concept of ******* social roles or how they view themselves. "This baby has a penis" is not an assignment. It is an objective recognition. "Assigned" carries the notion of variables or options. There are none at birth.
What may or may not be widely acceptable is not really the topic. The topic, as others have been hammering, is the UC Boulder guidelines, which are big ze advocates, as well as recommending ordering students to "never assume gender". That's getting silly. One can assume gender correctly probably north of 99% of the time, so there's literally no reason to play dumb during that big ol' 99%.
