Thank so much for an expanded explanation of this, and with scientific references. Transgender studies weren't really a thing when I was growing up, and I wonder how many of the "tomboys" and "sissies" of the 80s have brain atypical brain structures for the gender they were assigned at birth.

It's more than a bit ridiculous that we're still using scientific research to determine whether it's "ok" to just be yourself. Hopefully we'll move past that as a society sooner rather than later.
