"As someone who generally identifies as pretty far left, I am actually struggling to see how Transracial and Trangender are fundamentally different"

We should wait for that science before chopping kid's tits off. Adults getting spray tan and perm should be more accepted and held to lower standards of evidence than sterilizing children

If "androphillic transgender women" (i.e. homosexual males) "have a brain structure similar to cisgender women's," that still doesn't tell you if their brains are different from homosexual cisgender males. From your own article:

It should be noted that in homosexual men the volume of the INAH-3 was reported to be feminine.

Similarly, it's also peppered with sentences like:

MRI studies show that ICV in adult (Rametti et al., 2011b) and adolescent (Hoekzema et al., 2015) untreated homosexual MtFs is similar to male controls’.

Moreover, GM, WM, and CSF volumes in homosexual MtFs do not differ from those of control males and are significantly greater than those of control females (Table 4).

With respect to MtFs, Hulshoff Pol et al. (2006) found that before treatment subjects’ brain volume was consistent with their natal s*x.

So overall, MTF brains look like cisgender male brains. You strags just focus on one area (WHICH COULD BE LINKED TO S*X ATTRACTION) and claim there is a distinct trans brain phenotype. And note, this is one area that comes from doing a bit of p-hacking ("However, the results should be taken cautiously because of the small sample size and the brain statistical maps showing significance were at an uncorrected level (p < .001).")

Again, where are the studies looking at gynephilic transgender women and androphilic transgender men?
